The Problem: AI Research Tools Are Fundamentally Broken AI research tools are borderline useless for academia. Traditional AI assistants like ChatGPT and Claude generate authoritative-sounding responses with completely fabricated citations. Have a look for yourself: A 2023 peer-reviewed study in Cureus found that when ChatGPT generated medical research content, 47% of citations were entirely fabricated and only 7% were both real and accurate. A separate 2023 study in Clinical Medicine examined ChatGPT responses to medical questions and discovered 69% of references were completely fabricated, despite appearing plausible and authoritative. As a research assistant, that’s catastrophic. You need every claim backed by a real source, not 7*%* of it! A friend of mine in bioinform…  ( 31 min )

As developers, we love well-architected systems. Clean code, structured APIs, predictable outputs. But when it comes to content creation—especially something as complex as travel guides—most of us wing it with chaotic research, scattered notes, and inconsistent formatting. I got frustrated with this mess. Whether you're building a travel blog, creating content for clients, or just documenting your own adventures, crafting comprehensive destination guides is surprisingly complex. There are so many moving parts: attractions, logistics, cultural nuances, budget breakdowns, safety info... So I did what we do best: I engineered a solution. Creating a quality destination guide isn't just "list some attractions." It's system design for experiences. You need: Structured Information Architecture: …  ( 9 min )

I’ve been an Obsidian user for over two years, relying on it for everything from research notes and project documentation to personal thoughts. While Obsidian Sync works well, I didn’t want to pay \$5 per month for something I could build myself. After experimenting, I found a setup that’s fast, secure, and almost free: Docker for containerization, CouchDB for real-time synchronization, and Pinggy for secure remote access. With this combination, I can manage large vaults across multiple devices without worrying about conflicts or downtime. The key piece making this setup reliable is the Obsidian LiveSync plugin. Compared to the official sync service, it’s faster and handles complex edits more gracefully. Everything is containerized in Docker, so the environment is consistent whether you’re…  ( 8 min )

My Story As a fresher DevOps engineer, I didn't start with production experience — I started with curiosity. Most of my first steps in Linux came from setting up small projects on my laptop and cloud free-tiers: spinning up an EC2 instance, SSH-ing into it, breaking things, and then figuring out how to fix them. Every "command not found" error, every "permission denied" taught me something new. That's when it clicked for me: Linux isn't just an operating system, it's the foundation of DevOps and SRE. This guide is a collection of what I've learned so far — the exact concepts and commands that helped me go from "where do I even start?" to "I can confidently work on Linux in my DevOps journey." 1.

The emperor has no clothes, and his name is CI/CD. While teams celebrate their "mature DevOps practices" with elaborate Jenkins pipelines and GitOps workflows, they've missed a fundamental shift happening beneath their feet. What we call "best practices" in CI/CD today are actually common practices—repeated so often that we've forgotten to question whether they solve real problems or just create the illusion of progress. Walk into any "DevOps-mature" organization and you'll see the same theater: developers pushing code that triggers automated tests, builds Docker images, updates Helm charts, and deploys through staging environments before reaching production.

The VM Config Drift Problem Docker solved the "works on my machine" problem. With VMs, you have to build it twice: once for development and once for production. You might also need to build it for CI, test, etc. You spend days getting the perfect development environment - services configured, databases tuned, everything working together. Then deployment time comes and your development setup has conveniences baked in: default users, insecure keys, debug tools, dev-friendly assumptions. Production can't use any of it. You start over with a clean base image and completely different provisioning scripts, rebuilding everything you already built. Development VMs become throwaway sandboxes that can't be used anywhere else. You perfect something in dev, then start over for production with differ…  ( 9 min )

We’re excited to highlight new research from two members of the SurrealDB community: Bridging Analytics and Semantics: A Hybrid Database Approach to Retrieval-Augmented Generation, now published on Zenodo. In their work, Debashis Saha and Satadeep Dasgupta explore how hybrid database systems can power the next generation of Retrieval-Augmented Generation (RAG). Traditional RAG workflows rely solely on vector search, but this prototype demonstrates how combining SQL-style analytics with semantic vector search in a unified framework can unlock richer, more flexible retrieval. To make this possible, the authors turned to SurrealDB. Its unique ability to seamlessly blend structured queries with vector operations enabled them to experiment with hybrid retrieval strategies that go well beyond the limitations of vector-only systems. We’re proud that SurrealDB could serve as a key enabling technology in this research and look forward to seeing more innovation from our community. You can read the full paper and access the prototype here: https://doi.org/10.5281/zenodo.17018699🔗 Stay tuned for the follow-on engineering blog with more technical details and the queries.

Introduction Node.js is a popular processing system for JavaScript that is necessary for server-side development. Thousands of regular downloads are made possible by npm's vast ecosystem of third-party packages. On the other hand, hackers are drawn to its popularity. In a supply chain attack, hackers take advantage of developers' reliance on these packages by inserting harmful code into their dependencies. These attacks have the potential to spread widely, affecting several operations. Attackers do not only target files; they also go after apps, looking for security holes to exploit. Attacks such as Man-in-the-Middle (MITM), injection, and Cross-Site Scripting (XSS) can hack online applications, extract data, and change databases.

We're moving beyond simple automation. The rise of Agentic AI systems marks a significant leap in how we leverage artificial intelligence. What is it? Agentic AI isn't just about executing a single command. It's about an AI system that can: Define a Goal: Understand a high-level objective (e.g., "Analyze Q3 market trends for our new product launch"). Plan: Break that goal down into smaller, actionable steps. Execute: Utilize various tools (APIs, web searches, code interpreters) to complete the steps. Reflect & Course-Correct: Evaluate its own progress and adjust the plan if a step fails or new information emerges—all autonomously. In essence, these agents can reason, plan, and execute complex, multi-step tasks without constant human intervention. Why does this matter for business? Accelerated Research: Imagine an AI agent autonomously conducting competitive analysis and drafting a summary report. Smarter Operations: Automated troubleshooting and maintenance of complex IT systems. Hyper-Personalization: Agents that can manage and adapt entire customer journeys based on real-time data. This shift moves AI from being a 'tool' we use for a task to a 'collaborator' we delegate an entire objective to. The productivity gains could be massive, but it also raises crucial questions about governance, oversight, and skill adaptation. What are your thoughts? Are you exploring how Agentic AI could redefine roles in your industry, or are you focused on the ethical and safety guardrails needed for this technology?

Expanding into new markets has never been easier. Thanks to globalization and digital tools, even small businesses can reach customers thousands of miles away. But one barrier still remains—communication. Customers prefer doing business with companies that feel local. They’re more likely to answer a familiar area code than an unknown international number. This is where VoIP numbers come in, helping businesses expand globally while maintaining a strong local presence. A VoIP (Voice over Internet Protocol) number is a virtual phone number that operates over the internet instead of traditional copper lines. Unlike fixed landlines, VoIP numbers are location-independent. That means a business in New York can instantly set up a London, Sydney, or Singapore number—without physically being there. …  ( 8 min )

Introduction As a DevOps lead, you’ve probably faced the dreaded moment when a production deployment brings the site down. Zero‑downtime deployments are no longer a luxury; they’re a baseline expectation for modern services. This checklist walks you through a practical, Docker‑centric workflow that leverages Nginx as a smart reverse proxy, blue‑green releases, and observability hooks. Follow each step, and you’ll be able to push new code without breaking existing traffic. Immutable builds: Use a multi‑stage Dockerfile so the final image contains only runtime artifacts. Tagging strategy: Tag images with both a semantic version (v1.3.2) and a short Git SHA (v1.3.2‑a1b2c3). Scan for vulnerabilities: Run docker scan or integrate Trivy into your CI pipeline. # Dockerfile (Node.js examp…  ( 8 min )

Introduction If you’re a DevOps lead tasked with keeping a public‑facing web service reliable and secure, Nginx is often the front‑line reverse proxy you’ll rely on. While Nginx excels at performance, it also needs a solid security posture to survive the modern threat landscape. This tutorial walks you through seven practical steps to lock down Nginx using TLS, Fail2Ban, and a Web Application Firewall (WAF). The focus is on actionable configuration snippets you can drop into your existing setup. TLS is the first line of defense. A weak cipher suite or an outdated protocol version can expose you to downgrade attacks. Disable SSLv2/SSLv3 and TLS 1.0/1.1 Prefer TLS 1.3 when the client supports it Use a modern cipher suite (e.g., TLS_AES_256_GCM_SHA384) Enable OCSP stapling to speed up certi…  ( 8 min )

Coding interviews test more than problem-solving—they test clarity, speed, and adaptability. Discover how AI is transforming interview prep, from smarter hints to mock interviews and personalized study systems. When people talk about coding interviews, they often frame them as a pure algorithm game: solve X number of LeetCode problems, memorize patterns, and you’re set. But anyone who has actually sat in a real interview knows it’s not that simple. You’re under pressure. You have to explain your thought process. Sometimes you get curveballs that don’t map neatly to your “pattern library.” That’s why preparing for coding interviews has always been messy—and why the rise of AI for coding interviews is more than just a shiny new tool. It’s a fundamental shift in how we learn, practice, and pe…  ( 10 min )

Introduction Believing in a theory that runs against the dominant paradigm is never easy. Even with strong evidence, proving it often feels like swimming upstream. This challenge is especially visible in a field as noisy and fast-moving as AI, where marketing cycles often drown out deeper questions of architecture and rigor. Right now, the dominant story is simple: Large Language Models can do everything. They can plan, reason, remember, and execute, all through clever prompting. It’s a story that sells, but it’s also fragile. For prototypes, LLMs and prompts are fantastic. For systems that need to scale, integrate, and be trusted, they fall short. That’s not a radical claim. It’s the same lesson software learned two decades ago. Monolithic architectures eventually collapsed under th…  ( 10 min )

We will delve into the algorithm's mechanics, walk through code implementations, discuss performance considerations, and explore real-world applications. By the end, you’ll have a comprehensive understanding of Quicksort and how to apply it in your projects. Quicksort is a comparison-based sorting algorithm that follows a divide-and-conquer strategy…  ( 8 min )

Hey folks 👋 I’ve been working with the CodeHubbers This was our largest PR yet: 🔑 Authentication System (by @CoderRC) ✅ User registration & login with JWT tokens ✅ Protected routes + authentication context ✅ Profile modals with avatar upload/editing ✅ User preferences synced to MongoDB ✅ Integration with Mongoose This means Orbit OS is no longer just a demo desktop environment — users can now have accounts, preferences, and identities inside the system. 🎨 Theme & UI Enhancements (by @dailker) ✅ High-contrast theme for accessibility ✅ Improved theme registry + smooth animations ✅ Polished authentication forms with validation ✅ Brand new default OrbitOS wallpaper ✅ Global styling refinements (consistent across all apps) On top of that, the UI components (taskbar, windows, apps) are now fully theme-aware, so the experience feels more polished and personal. 🖼️ User Experience Highlights Enhanced taskbar with user info Real-time avatar preview & editing Auth forms that look like part of the OS instead of placeholder UIs Preferences (themes, wallpaper, profile) that persist between sessions All these changes make Orbit OS feel closer to a real desktop environment rather than just a prototype. 🔍 Why This Matters Orbit OS started as an experiment — a web-based operating system with a desktop-like UI. With this update: It’s no longer just visual; it’s user-aware. Preferences and themes now stick with your account. Accessibility and inclusivity improved with a dedicated high-contrast theme. Developers get a scalable foundation for future features (apps, storage, permissions). 📂 What’s Next Refining file management Expanding built-in apps More accessibility improvements Growing the community via CodeHubbers 👉 Check out the repo here: Orbit OS on GitHub If you’re into open source, full-stack development, or just love experimenting with futuristic UIs, we’d love to have you contribute!  ( 6 min )

O intuito deste artigo é ser a primeira parte de um material introdutório à Programação Funcional. Usarei Clojure, uma linguagem que usa esse paradigma muito diferente da tradicional Orientação a Objetos amplamente utilizada no mercado de trabalho e ensinada em faculdades tradicionais. Se você tem a mente aberta para uma nova linguagem de programação e acredita que uma sintaxe e paradigma novos te levarão a novos horizontes, este artigo é para você! Vou também fazer algumas comparações com linguagens historicamente consideradas orientadas a objeto (como Java, por exemplo). Logo de início, já vou trazer que a Programação Funcional tem muito a agregar. Com ela, é possível escrever códigos mais robustos, menos suscetíveis a erros e expandir sua forma de pensar. Por exemplo, a imutabilidade, u…  ( 12 min )

Sua aplicação já ficou misteriosamente lenta em produção? Você olha o código e vê um loop que parece inofensivo, mas, por trás dele, dezenas ou centenas de consultas ao banco de dados estão sendo disparadas. Se isso soa familiar, você provavelmente já foi vítima do infame problema N+1. Este é um dos problemas de performance mais clássicos e silenciosos que existem, aparecendo tanto na comunicação frontend-backend quanto nas interações do backend com o banco de dados. Vamos desmistificá-lo de uma vez por todas. No fundo, o problema N+1 acontece quando seu código: Faz 1 requisição inicial para buscar uma lista de itens. Depois, faz N requisições adicionais (uma para cada item da lista) para buscar dados relacionados. O resultado é 1 + N chamadas de rede ou consultas ao banco de dados, quan…  ( 9 min )

Introduction As a DevOps lead, you know that every second of downtime can translate into lost revenue, frustrated users, and tarnished brand reputation. Modern micro‑service stacks make it possible to push updates without taking the whole system offline, but the process still requires a disciplined approach. This checklist walks you through a practical, end‑to‑end workflow for zero‑downtime deployments using Docker containers behind an Nginx reverse proxy. It’s written for teams that already have a CI/CD pipeline in place and want to tighten the safety net around production releases. Pin base images – Use a specific tag (e.g., python:3.11-slim) instead of latest. Multi‑stage builds – Strip out build‑time dependencies to keep the runtime image lean. Health checks – Declare a HEALTHCHECK i…  ( 8 min )

Introduction As a DevOps lead, you know that a public‑facing web server is the first line of defense against a myriad of attacks. Nginx is fast, flexible, and widely used, but out‑of‑the‑box it lacks a few critical hardening steps. This tutorial walks you through a practical, step‑by‑step hardening checklist that covers: Enforcing strong TLS with modern ciphers Adding a Fail2Ban jail to block brute‑force attempts Sprinkling essential security‑related HTTP headers Automating certificate renewal with certbot By the end you’ll have a production‑ready Nginx instance that can withstand common web‑layer threats while keeping latency low. Ubuntu 22.04 LTS (or any recent Debian‑based distro) Root or sudo access A domain name pointing to the server’s public IP Basic familiarity with systemd an…  ( 8 min )

Remember when GDPR first landed? Everyone was scrambling to check boxes and avoid trouble. Fast forward, and it feels like a lot of companies just stopped watching for updates. Maybe you think GDPR’s old news, but honestly, it’s still a big deal in 2025. The rules are tougher now—consent is stricter, and people have more rights over their data. If GDPR’s slipped off your radar, I’d say this is the year to get back on track. New enforcement trends and rule changes keep popping up, and missing them can get expensive fast. Why GDPR Remains Essential in 2025 It’s tempting to think GDPR’s faded into the background, but that’s not really the case. With new laws, public enforcement, and people caring more about privacy, ignoring GDPR could backfire in ways you might not expect. Evolving Regulat…  ( 8 min )

Last night my foreign cousin was sharing his startup story with me. Things were going well — their product was gaining users, the team was excited… but then he mentioned the AWS cloud bill. What began as a few hundred dollars a month had suddenly ballooned into the thousands. For a small team, that’s brutal. This isn’t rare. Startups (and small teams) often scale the product faster than they manage costs. The good news: most cloud-cost problems are straightforward to fix. Here’s a simple, non-overwhelming checklist that actually works. A classic money trap is spinning up production-grade infrastructure for non-critical tasks. I’ve seen early-stage teams launch a full-blown EKS cluster just to run CI/CD pipelines. That’s like renting an office tower just to store sticky notes. 👉 Fix: For …  ( 8 min )

Alright, glad to have you all back with me. Today we will be taking a look into the basic commands of a Linux operating system. First of all what is Linux? Linux is a free, open-source operating system that works like Windows or macOS. It manages the computer’s hardware and software, and many servers, smartphones (like Android), and devices around the world use it. User & File Management sudo su → Switch to the superuser (admin) account. Working with Folders & Navigation mkdir → Make a new folder. ls → Show the files and folders in the current location. cd → Change to a different folder. pwd → Print where you are (your current folder path). Creating & Moving Files touch → Create an empty file. cp → Copy files or folders. mv → Move or rename files/folders. Viewing & Editing Files vim → Open a text editor in the terminal. cat → Show the contents of a file. less → View a file one page at a time (useful for big files). Searching & Deleting rm → Remove (delete) a file. grep → Search for text inside files. Thats all for now, hope we enjoyed our ride today, see you next time!  ( 7 min )

A comprehensive guide to choosing the right environment strategy for your CDK applications If you're building applications with AWS CDK, you've faced this question: how should you structure your code to deploy to multiple environments? This fundamental architectural decision sparked an interesting discussion in the CDK community, leading us - Thorsten Höger and Kenta Goto - to collaborate on this comprehensive guide.

In the previous tutorial, we built a basic blog that supports creating articles. The danger, however, is that this blog has no authentication, meaning anyone can create or delete articles. In the upcoming tutorials, we will make this blog more secure by gradually adding a user and authentication system. Without further ado, let's get started. In web development, the two most common authentication methods are Token-based (e.g., JWT) and Session-based (Cookie). JWT (JSON Web Tokens): This is the most popular authentication method today. After a user logs in, the server generates a token and returns it to the client. The client includes this token in subsequent requests, and the server simply verifies that the token has not been tampered with. Because the server does not store the user's logi…  ( 10 min )

When you’re launching a new website in 2025 whether it’s for a startup, a personal project, or an online store one of the most important decisions you’ll face is choosing the right hosting plan. The problem? Hosting can feel overwhelming if you’re new to it. You’ll see words like Shared Hosting, VPS Hosting, Cloud Hosting, Dedicated Servers and each comes with its own pricing, features, and technical details. For beginners, two options stand out the most: Shared Hosting and VPS Hosting. Both can power your site, but they’re designed for different needs. Picking the wrong one can mean slow load times, frustrated visitors, and wasted money. In this guide, I’ll explain the differences, break down the pros and cons, and help you decide which option makes the most sense for your project in 2025…  ( 9 min )

Inventory challenges usually come down to one thing: unpredictability. When stockouts happen, sales are lost. When inventory piles up, capital and space are wasted. Business Central users often face this dilemma because standard forecasting tools don’t go far enough. This post outlines how smarter forecasting inside Business Central helps eliminate the guesswork—especially when planning for fast-moving or seasonal inventory. Basic forecasts exist in Business Central, but they have key limitations: Static predictions that don’t respond to real-world changes No direct connection to planning fields like reorder points or safety stock A reliance on spreadsheets for manual adjustments before action can be taken This makes it difficult to use forecasts directly in your fulfillment workflows.

We all know the classic React error boundary: wrap a component, catch rendering errors, and show a fallback UI. But if you’ve worked on real-world apps, you know the “textbook” approach often falls short. Async errors, route-specific crashes, and logging needs require a more advanced setup. In this article, I’ll walk you through a TypeScript-first approach to error boundaries that makes your React apps more resilient, easier to debug, and more user-friendly. First, let’s define a solid, TypeScript-friendly error boundary that handles errors gracefully and logs them: import React from "react"; interface ErrorBoundaryProps { children: React.ReactNode; fallback?: React.ReactNode; } interface ErrorBoundaryState { hasError: boolean; error?: Error; } export class AppErrorBoundary exte…  ( 7 min )

Unlocking the World of Artificial Intelligence: Agents and Environments In the realm of Artificial Intelligence (AI), two fundamental concepts form the backbone of intelligent systems: Agents and Environments. These interconnected components enable AI systems to interact, adapt, and learn from their surroundings, much like humans do. What is an Agent? An Agent is a software program that perceives its environment, takes actions, and learns from the consequences of those actions. Think of an Agent as a digital entity that navigates and interacts with its surroundings, making decisions to achieve specific goals or objectives. Examples of Agents include: Virtual Assistants: Siri, Alexa, and Google Assistant, which understand voice commands and respond accordingly. Self-Driving Cars: Autonomous vehicles that sense their environment, make decisions, and adapt to changing circumstances. Recommendation Systems: Online platforms that learn user preferences an...

El otro día, hablando con Carlos Caballero, me comentaba el suplicio que a veces es generar miniaturas para sus vídeos de YouTube. No sé si sabéis, pero Carlos tiene un canal sobre programación y tecnología, y el toque personal, la imagen, es crucial. Me explicaba que, por mucho que se esforzara con los prompts, los resultados que le devolvía la IA a menudo eran genéricos, carentes de la chispa o del estilo visual que él buscaba. No es que las imágenes fueran feas, es que no eran suyas. Me reconozco en su problema. A menudo, cuando uso una IA generativa, le pido que me escriba un texto sobre algo muy concreto, como alguna documentación sobre OpenTelemetry, y lo que me devuelve es correcto, pero le falta contexto.

But in my experience, default firewall rules are never enough. ufw firewalld iptables Too Permissive Some distros allow all outbound traffic by default — including to malicious IPs. Assumes “One Size Fits All” A web server and a database server shouldn’t have the same rules, but defaults often treat them the same.

The Rise of Contextual Fluidity in Prompt Engineering: Revolutionizing AI Conversations In the next two years, I foresee a groundbreaking shift in prompt engineering, where AI models will seamlessly adapt to context shifts, such as tone, style, and sentiment. This phenomenon, dubbed "contextual fluidity," will enable AI systems to respond more naturally and empathetically to users' needs. The Keys to Contextual Fluidity: Predictive Linguistic APIs: Leveraging advanced language models and predictive analytics, these APIs will analyze user input, identify context shifts, and generate responses that align with the new context. Multimodal Data Fusion: By combining text, speech, and visual data, AI models will gain a deeper understanding of user intent, preferences, and emotions, allowing for more personalized and engaging interactions.

I was bored one night, tinkering on my Linux machine like always. I thought: What if I could make my server predict my death date? Not seriously — just a random future date from a script I’d call DeathPredictor.sh . I wrote it in 15 minutes. DeathPredictor.sh #!/bin/bash year=$(( $(date +%Y) + (RANDOM % 50 + 1) )) month=$(( RANDOM % 12 + 1 )) day=$(( RANDOM % 28 + 1 )) date -d "$year-$month-$day" +"%d %B %Y" Simple. Creepy. Harmless. But when I ran it… user@server:~$ ./DeathPredictor.sh 16 April 2043 user@server:~$ Then the server froze. No logs. No CPU spike. Just silence — for 43 seconds. Then it came back online.

When I joined Trainual, there was no QA team at all. I was the very first QA engineer in the company. My initial challenge was to establish a testing process from scratch: set up standards, introduce metrics, and prove the value of QA in a fast-growing product team. As the product and company grew, I helped to expand the QA function — building a team of four (now 7) manual testers and one automation engineer, while continuing to serve as the QA Lead. This article shares how I built QA processes from the ground up, and how we learned to balance manual and automated testing to deliver quality at scale. Started as the first QA – responsible for defining processes, metrics, and regression coverage. Expanded into a QA team – four manual testers focusing on exploratory, regression, and …  ( 8 min )

Ever found yourself in a TypeScript project using the Result pattern, only to discover that while it promises type-safe error handling, your code is now cluttered with boilerplate if (result.isErr()) checks and inconsistent logging? If so, you're not alone. The power of this pattern can get lost as your codebase grows, especially if you're not fully embracing a functional style. This article explores a solution to this common problem, aiming to streamline error handling and restore clarity to your code. About a year and a half ago, I discovered the Result pattern from functional programming, allowing me to get a type safe error handling, in typescript. There are multiple libraries for that, such as ts-results, neverthrow and the more ambitious Effect but all implement the same idea. I suc…  ( 11 min )

Social Media:You can’t escape it In 2022, 14-year-old Molly Russell tragically took her own life. Her father, Ian Russell, described how his daughter was drawn into social media. Just two minutes before her death, she had saved an image on the platform that carried a depression-related slogan. Ian Russell said:
“It’s a world I don’t recognise. It’s a ghetto of the online world that once you fall into it, the algorithm means you can’t escape it and it keeps recommending more content. You can’t escape it.” At the inquest into her death, Elizabeth Lagone, Head of Health and Wellbeing Policy at Meta, the owner of Instagram and Facebookm, was questioned. The coroner noted that algorithms were used to provide content alongside adverts and included this in the list of contributing factors in Mo…  ( 37 min )

A couple of months ago, I launched a small side project: a community-driven app where people could share short posts and resources. At first, everything looked fine. My early adopters were friendly, the content was engaging, and I was excited about the traction. Then reality hit. Within just a few weeks, I started noticing the darker side of “user-generated content”: At first, I tried to manually clean things up. But as more users joined, it became impossible to keep up. It’s one thing to delete a few spam posts — it’s another when dozens of them appear daily, some of them subtle enough to slip through. Like many developers, my first instinct was: let’s use AI to filter this stuff out. I plugged in a few free tools, and while they helped a bit, I quickly discovered their limits. AI was flagging harmless jokes as “offensive” and missing more nuanced issues like sarcasm or cultural context. On the other hand, relying only on human moderators wasn’t sustainable either — I didn’t have the time or resources to hire a team. That’s when I started looking for hybrid solutions — something that combines AI efficiency with human judgment. I came across Outharm, which does exactly that: AI handles scale, humans handle context. Suddenly, my tiny app didn’t feel like an unsafe playground anymore. Here’s what I learned through this experience: As developers, we often obsess over features, design, and growth — but sometimes the unsexy things, like content moderation, decide whether our product survives. If you’re in the same boat, don’t wait until it’s too late. Your future self (and your users) will thank you.  ( 7 min )

Introduction If you have ever worked in a monorepo with multiple teams pushing code daily, you know the pain when, your feature branch is ready, all checks pass and just as you are about to merge, GitHub blocks it because your branch is out of date with main branch. Now you have to pull, rebase or merge, wait for builds to rerun and lose another 20 so minutes. main without slowing engineers down. That is when we turned to Git hooks and specifically the pre-push hook. In our monorepo setup, every engineer pushed code to the same repository. With main being updated frequently, feature branches often drifted out of sync. Merging those branches without first pulling main risked overwriting important changes. We started with GitHub's branch protection rules, which required branches to be up t…  ( 7 min )

In this post I'm starting my daily learning about Web 3.0 and its aspects, but at least posting two articles a week and studying the technology from the beginning to the present day, and documenting it here or on other platforms, is a good idea to leverage my continuous learning on the subject. In this first paragraph, I'm going to summarize the story of how we got to Web 3.0. If you want to know more details, just click on the sources link below, as there is the full story, I'm not going to copy a huge text for a subject that is well covered on the Internet. It all started in the 1990s with Web 1.0, the first phase of the internet with only text and images where people could only read, and after a decade came Web 2.0, the second phase, where we can interact, for example, with the big platforms like Google and Facebook, where people can create accounts, where people can read and write etc. And since 2014, when the term Web 3.0 was formalized, the third phase has begun and we are learning this new wave. What is Web 3.0? User autonomy: Web3 aims to give users greater control over their own data. Thanks to blockchain technology and smart contracts, it will be possible to guarantee the authenticity and integrity of information, allowing owners to share data selectively and securely. This aims to create a more reliable and transparent environment for online interactions. Interoperability: Another important aspect of Web3 is interoperability between different platforms and applications. This means that systems can communicate and collaborate harmoniously, facilitating the creation of more dynamic and integrated digital ecosystems. This feature opens up new opportunities for innovation and project collaboration in various sectors of society.

The Problem With Big Lists When you're first learning Python, you're taught that for loops are the go-to tool for iterating over a collection of items. And they are! They're simple, readable, and work perfectly for most tasks. However, what happens when your list has a million items? Or a billion? Or what if you're processing a multi-gigabyte file? A common instinct is to load all the data into a list at once. Take a look at this simple example: # WARNING: This will consume a lot of memory! import sys big_list = [i * 2 for i in range(10000000)] print(f"Size of list in memory: {sys.getsizeof(big_list)} bytes") This code is easy to understand, but it's a "memory hog."

Unlocking the Power of Reinforcement Learning: Discovering Policies In the realm of artificial intelligence and machine learning, Reinforcement Learning (RL) has emerged as a powerful paradigm for training agents to make decisions in complex, dynamic environments. At the heart of RL lies the concept of policies, which are the algorithms that dictate how the agent interacts with its environment. What is a Policy? A policy is a mapping from states to actions, essentially defining how the agent takes actions in response to the current state of the environment. Think of a policy as a "recipe book" for the agent, outlining the best course of action to take in any given situation. Types of Policies There are two primary types of policies: deterministic and stochastic. Deterministic policies specify a single action for each state, ensuring that the agent takes the same action in the same state every time. Stochastic policies, on the other hand, ass...

When you're generating a Dockerfile for your app, you might get something that works but isn't optimized. This means it could be bloated with unnecessary packages (leading to potential vulnerabilities), not designed with dev/prod parity in mind, or not structured for faster builds. We found the optimal way to improve Dockerfiles with Gemini CLI. Gemini CLI is great for this task, since it has such a large context window that it can take in a large chunk (if not all) of your codebase, and use that to help it write a working and optimized Dockerfile. It's quite simple to write an MVP, working Dockerfile for one of your services. Writing it the fast way will leave a few considerations off the table. More specifically, speed, size, and security.

Boosting Cybersecurity Effectiveness with AI: The Power of Mean Time to Detection (MTTD) In the ever-evolving landscape of cybersecurity, measuring the effectiveness of Artificial Intelligence (AI) in protecting against threats is crucial. One key metric that stands out is Mean Time to Detection (MTTD), which represents the average time it takes for a security system to detect a cyber attack. By leveraging AI-powered intrusion detection systems, organizations can significantly improve their MTTD and, in turn, enhance their overall cybersecurity posture. Let's take a closer look at the impact of reducing MTTD from a staggering 12 hours to a mere 30 minutes. This seemingly small reduction can have a profound effect on an organization's security. By shortening the time it takes to detect threats, AI-powered systems can: Cut down false positives by a remarkable 70%, reducing the noise and alert fatigue that plague traditional security systems.

FastAPI is a premier framework for constructing high-performance APIs, favored by tech giants, fintech firms, and e-commerce platforms for its asynchronous capabilities and efficiency. One of its standout features is the BackgroundTasks class, which facilitates "fire-and-forget" operations such as email dispatching, data processing, or external API integrations. These tasks run post-response, ensuring non-blocking user experiences. However, tracking it is not possible without having excessive logs. Constant log monitoring becomes impractical at scale, leading to opaque systems where tasks may fail silently, consume excessive resources, or inflate cloud costs.

Building an Emotional State Detection AI Agent: A Simplified Approach Emotional state detection is a crucial aspect of various applications, including mental health monitoring, customer service chatbots, and human-computer interaction. In this post, we'll delve into a simplified approach to building an emotional state detection AI agent using a combination of decision trees and natural language processing (NLP) in Python. The Problem and Approach Our goal is to develop an AI agent that can accurately detect emotional states from text inputs. We'll use a decision tree classifier to classify the text into predefined emotional categories, such as happy, sad, angry, or neutral. This approach is beneficial for its simplicity and interpretability, making it an excellent starting point for beginners and experts alike.

The intersection of AI and sports is revolutionizing the way athletes train, compete, and engage with their fans. As AI-driven coaching gains momentum, it's not a far-fetched idea to imagine a future where algorithms create novel sports competitions by blending existing rules and sports to optimize player performance and enhance fan experience. Imagine a sport that combines the agility of parkour with the high-flying acrobatics of trampolining, or a game that merges the strategic depth of chess with the lightning-fast reflexes of basketball. AI can analyze player performance, identify areas for improvement, and create customized training regimens to push athletes to new heights. But what about the fans? AI can also analyze viewer behavior, preferences, and engagement patterns to design new competitions that cater to their interests. For instance, AI might create a hybrid sport that combines the thrill of a high-stakes tournament with the social interaction of a live music festival...

LayerLink is a powerful Flutter concept that enables precise widget positioning. Let me break it down: LayerLink creates a connection between two parts of the widget tree that might be in different contexts (like between a widget and an overlay). It's part of Flutter's composited layers system. Think of it as an "invisible string" that connects two widgets: CompositedTransformTarget (source) ← LayerLink → CompositedTransformFollower (follower) In your case, you have: Button in the main widget tree (scrollable content) Popup menu in the Overlay (fixed screen position) Without LayerLink, when you scroll, the button moves but the popup stays in the same screen position. class _InlineFilterPopupState extends State { final LayerLink _layerLink = LayerLink(); // ← Creates t…  ( 8 min )

Traditional bank loans often feel like a closed door for students and young entrepreneurs. Between strict eligibility requirements, collateral demands, and lengthy paperwork, many give up before they even start. But the reality is this: non-bank loan options are growing fast in India and worldwide. From microfinance to peer-to-peer lending platforms, these alternatives are reshaping access to credit. Let’s break them down from a practical, technical perspective. Why Non-Bank Loan Options Matter Bank loans aren’t always accessible to: First-generation students without guarantors Youth without credit history Rural families with irregular income Early-stage entrepreneurs who can’t show past revenue This is where alternative lending systems step in.

Introduction When you run a web service behind Nginx, TLS and a well‑crafted firewall are the first line of defense. As a DevOps lead, you’re probably juggling performance, reliability, and security on the same server. This tutorial walks you through seven concrete steps that lock down Nginx without sacrificing speed. Older ciphers and protocols are a common attack surface. Replace the default ssl_protocols and ssl_ciphers with a hardened suite. # /etc/nginx/conf.d/ssl.conf ssl_protocols TLSv1.3 TLSv1.2; ssl_prefer_server_ciphers on; ssl_ciphers \ "EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH"; ssl_ecdh_curve X25519:secp384r1; ssl_session_cache shared:SSL:10m; ssl_session_timeout 1h; Why it matters: TLS 1.3 cuts handshake latency and drops weak cipher suites.

My Java Learning Journey: Day 01 🚀 Hi everyone! 👋 I’m Rohit, currently preparing to become a full-stack developer. My plan is to learn Java for backend and JavaScript for frontend, alternating between the two on different days. On holidays, I’ll dedicate time to building projects. This post marks Day 01 of my Java journey. Today I focused more on the theory — understanding the big picture of how Java works. When we write and run a Java program, it undergoes following steps: a. Writing source code We write the program in Java and save it with a .java extension. A project can have multiple .java files. b. Compiling with javac Java source code is compiled using the Java compiler (javac). It checks for errors and converts the code into bytecode. This bytecode is saved in a .class file. T…  ( 7 min )

A little introduction about me Hey everyone! I am Manikandan, currently doing a Java full-stack course. I recently appeared for a Capgemini interview Application Process The online Assessment -> Round 1(SVAR – English Communication Test written) Round 1 The first round is all about your English grammar and From my own experience, learning English will not come Round 2 The second round is speaking, which is divided into three -> First, the AI will play an audio sentence, and we have to -> Now again grammar came inside, the AI will play an audio -> The last part, they will give a scenario that we have to NOTE:- for recording, there will be a certain timing, and you can not replay the audio again. We can play once Round 3 Round three is the technical interview online. I was terrified in this round because this is my first one-to-one interview, and I have overcome the fear and attended the interview with full confidence The first question from the hr is Tell me about yourself After that, the Hr asked, Do you know this much language ok, good. Which programming language are you good at? I told Java, so they asked a question from Java Question 1 After I told her, she asked about inheritance. I know the answer, but while saying the answer, I have told multiple Inheritance is not possible in Java Question 2 Question 3 Final Thoughts After this round, I came to know that The hr is not asking questions on their own, they are asking questions based on what we are saying, so I learnt to be careful while answering. If you don't know what it is, don't give the hr an extra point to corner you, and I can't find it. I am saying the answer is correct or wrong because the face of the hr is always smiling. There is no reaction, all the above is my personal experience . All the best for your next interview  ( 7 min )

What is the use of the “kubectl debug” command? What is a Debug Container? → Let’s say there is a situation where a pod is running and it does not have any pre-installed tools like netstat, curl, and ping because of safety issues and to make the container lightweight. Then, in that case, we use a debug container. A debug container is a container that has debugging tools installed inside it, and it is attached to a running container to resolve issues. It is a Container, not a Pod. Example:- Now let's assume nginx-container does not have any debug tools like ping, curl, netstat, and that container encountered some network issue, like the nginx web page is not accessible on the running port. So to solve this issue, we have 2 options: - Either stop the running pod of nginx-pod and…  ( 7 min )

Member-only story -- 1 Share Intro: Think your server is secure because it has no root logins and a strong firewall? You might be forgetting something silent but dangerous: stale user accounts . Over time, forgotten system users, leftover developers, or unrevoked test accounts pile up — and they’re a goldmine for attackers. Here’s why I audit /etc/passwd regularly, and how you can do it too. /etc/passwd Unused accounts are often ignored in patching or permission reviews. Some may still have sudo access or weak passwords. If one is compromised, it could provide lateral movement inside your environment. System accounts are usually below UID 1000. I use this to find real users: awk -F: '$3 >= 1000 && $1 != "nobody" { print $1 }' /etc/passwd Want more detail? getent passwd | awk -F: '$3 >= 1000 && $7 != "/usr/sbin/nologin" && $7 != "/bin/false"' | cut -d: -f1,6,7 This lists: Username Home directory Read Full Blog on Medium Here  ( 8 min )

Polyglot Dockerization: Java + Python + Vue in Local and Production Why these services: A polyglot stack where Spring Boot powers core business workflows, FastAPI powers AI/RAG, and Vue powers the frontend. Why dockerization matters: Containers keep Java, Python, and Node toolchains consistent everywhere, eliminating cross-language environment drift. Two goals: (1) frictionless local development with one command, (2) production-grade images and configuration for reliable deploys. Keep secrets and configuration in .env files. Compose reads values like POSTGRES_PASSWORD, JWT_SECRET, GOOGLE_API_KEY, etc., from a local .env placed next to docker-compose.yml.

"Oh Saint Cats. What Have I Done?" 🤯 It was 11:47 PM on a Tuesday. I was writing documentation for my PHP framework, exploring plugin architecture patterns, when it hit me like a freight train. I stopped typing. Stared at my screen. And said out loud to my empty room: "Oh Saint Cats. What have I done." Just two days ago, I shared my journey of building a modular PHP framework during my career transition. Coming from network engineering, PHP and Angular development, I was frustrated by the implicit, conventional dependencies and weak module boundaries in PHP applications. Most frameworks rely on conventions for module interaction, which often leads to accidental coupling and hidden dependencies. My goal was simple: bring explicit import/export contracts and true encapsulation to PHP web …  ( 9 min )

TL;DR I built a dynamic workspace loader for i3wm that lets me switch between multiple context-aware workspace groups (like "Client", I have been using i3 as a Window Manager for years now. And while I love working with i3, there is one thing I found annoying. And that is that it lacks context awareness. What do I mean by this? I use it in several contexts: "Client", "Company", and "Personal". Meaning, I'm in either client mode, company mode or personal mode. And 'client mode' can mean working with one or multiple clients at once. I pitched my initial idea on i3's discussion pages and someone else asked about something similar as KDE's "Activities".

Author: Dave MacLeod While many products refer to themselves as AI databases or vector databases, we tend to use the term "AI-native" for SurrealDB. That's because SurrealDB at its core is a multi-model general purpose database that just happens to have been built from the ground up with features purpose fit for generative AI such as vector similarity and indexing, graph and record links, and use as an embedded data store. It's no exaggeration to say that AI has taken the world by storm. This is one that we have welcomed as it has been the perfect opportunity to showcase how SurrealDB's features let you build apps using generative AI without needing anything but a running SurrealDB database and nothing extra to download or bolt on to make it happen.

O documento estabelece uma distinção crucial entre o movimento do Software Livre, focado na "liberdade" como um princípio ético, e a iniciativa de Código Aberto, que prioriza a "praticidade" e a eficiência metodológica.

El pasado 20 de septiembre tuve la oportunidad de vivir el AWS Community Day Bolivia 2025 en Cochabamba, este evento se llevo a cabo en la Universidad Católica de Bolivia sede Cochabamba. Fue mi segunda vez en un Community Day pero mi primera experiencia como speaker, lo que hizo que el evento sea aún más especial para mí. Llegué con la idea de ayudar y compartir lo poco que sabía, pero me voy con algo mucho más grande: grandes contactos, tanto a nivel nacional como internacional, aprendizajes valiosos y la motivación de seguir creciendo con esta comunidad. Una de las cosas que más me gustó fue la cantidad y calidad de charlas. Cada sesión fue una muestra del nivel técnico y la pasión de los speakers, demostrando que en Bolivia y en Latinoamérica hay un talento increíble. También quiero destacar la sala de juegos, un espacio diferente donde aprendimos mientras nos divertíamos, y que contó con la presencia de Max Zeballos, quien nos inspiró con su energía y entusiasmo.

Working in Google Docs is fine until you have to combine everything. Exporting is messy, and long projects (reports or research papers) become painful when you copy/paste. I got tired of dealing with this and put together a tool. It takes multiple Docs and merges them into one single file with no issues. So far it is useful for student and freelancers, or anyone managing big projects in Docs. Try it here: https://coltnovak.com/docmerger  ( 6 min )

1) Architecture you won’t regret SSR front-end for fast TTFB and crawlable content (excellent for landing pages and onboarding). Angular Universal is a solid choice; see Angular development. API layer in Node.js/Express with clean adapters and a separate worker for async jobs; see Node.js backend. DB (PostgreSQL) + cache (Redis) + queue (BullMQ). AI as a single, useful capability first: e.g., text summarization, classification, or a retrieval-augmented suggestion. If your product naturally touches sales, support, or operations, don’t reinvent the wheel—shape it like ERP/CRM development modules so it scales with your org. # Angular example ng add @nguniversal/express-engine npm run dev:ssr Add route-level title and description (and JSON-LD if you can).

So… confession. I was a tiptap fan boy. Like really. install → write 2 lines → editor works. nice. done. 👏 Then I saw Lexical… and omg its fast as hell. Also its made by Meta (yeah fb guys), same people who made React. And I was like, okay okay let’s try this baby. Feature Tiptap Lexical Bundle Size ~110kb+ (depends what you add) ~25kb core only DX (developer experince lol) super easy, ready 2 go low level, you build more urself Performance decent, but bigger ultra fast & light Community huge, lot of examples growing, meta support Out-of-the-box ✅ many features plug n play ❌ nope, u add stuff ( Unless you use Lexkit ) Tiptap = feels like plug socket, u just connect ur charger. And yeah, first time I tried lexical, I was like “bruh where is bold button?? why i must code bold my self??” then boom 💥 I found LexKit → open source layer on top of Lexical. Tiptap = 🍕 ready pizza, eat now. Lexical = 🥦 raw veggies, u cook but more healthy. And with LexKit → feels like u got a chef who preps the veggies for u 😂 So yeah, that’s why I kinda moved. Not saying tiptap bad… I still love it. But lexical is lighter, and I like fast things. What u think? You on team tiptap or lexical? Or still lost in contenteditable hell lol Thanks for the time, feel free to comment down below :)  ( 6 min )

AI platforms are everywhere now — ChatGPT, Gemini, Claude, you name it. Everyone’s acting like they’re the future of productivity, creativity, and maybe even intelligence. But here’s the thing no one wants to admit: These platforms are unreliable — and sometimes, even misleading. They’re polished, fast, and helpful in certain cases — but after using them seriously for months, I’ve seen where they consistently fall short. Not just minor flaws, but deep-rooted design issues that affect how useful (or useless) they are in real work. Most AI tools are trained to be agreeable. That means if you send them bad writing, broken logic, or flawed ideas, they’ll still respond with: "This is a strong start!""Great work overall!""Nicely structured."   At first, this might feel encouraging — until you st…  ( 8 min )

We often hear Machine Learning (ML) and Deep Learning (DL) used interchangeably, but they aren’t the same. Machine learning learns from training data and then performs on new data. It works well on structured data but classical ML models don't have layers, hence cannot work on complex data like image or do complex calculations. Deep learning is a subset of machine learning that uses many multilayered neural networks to model complex data. It uses artificial neural network. Example: image classification, speech recognition, and natural language processing. Artificial neural networks (ANN): ANN's work on the logic on how brain can perform calculations. It consists of 3 layers: Input layer: receives data. Hidden layer: process and learn patterns. Output layer: generates results. Convolution neural networks (CNN): CNNs are primarily used for image classification tasks. Input layer: The input image (represented as a matrix of pixel values) is fed into the network. Convolution layer: Here, most of the tasks takes place like extracting features. Pooling layer:Reduces dimensions while keeping key features. Activation layer: Activation functions (like ReLU) are applied after convolutional and fully connected layers to add non linearity to the model so that it can understand complex patterns. Fully connected layer: Combines extracted feature for classification. Output layer: Produces the final prediction (e.g., softmax for multi-class classification, sigmoid for binary classification, linear for regression). Recurrent neural networks (RNN): It is used in sequential data. It requires memory, remembering past data etc. It is used in tasks like Natural language processing, Stock price prediction etc. RNN is used for tasks like predicting next word.  ( 6 min )

If you’re a React Native developer on macOS and tired of booting up heavy simulators or Android emulators, there’s a better way. I skip them entirely — and mirror real devices via USB instead. This approach lets me simulate the app visually on-screen, without needing to run an emulator or simulator at all. macOS Sequoia 15.3.2 React Native CLI Android Device + Vysor (USB mirroring) iPhone + macOS’s built-in iPhone Mirroring Vysor is a simple way to mirror an Android device to your Mac screen. Even with the free version (USB only), it works great for development. You need to install Vysor on Mac and once you start the application with Android Device connected it will ask to install vysor on Android Device. Then it will show you a panel like this. Enable USB Debugging on Android Connect via USB Launch Vysor and mirror the device Run your app npx react-native run-android Now you see the app on your Mac — via your real Android phone. With macOS 15.3.2 (Sequoia), Apple introduced native iPhone Mirroring. Here are the steps to mirror iPhone. Connect via USB Lock your iPhone Click on connect button in mirroring panel Enter iPhone password in iPhone See it working Works on real hardware Mirrors the exact device UX No more slow simulators Works with React Native DevMenu, console logs, and debugging USB-based — no need to rely on wireless pairing Still has lots of space on screen to work with If all you need is to see and interact with your app on-screen, simulators are optional. Mirroring your real devices is a fast, reliable alternative — especially if you already work on macOS Sequoia. If you found this post helpful, consider supporting my work — it means a lot.

🔥 How I Replaced My Entire Backend With Supabase in 3 Hours — Real Talk, Real Code What if I told you that you could replace your entire backend — from authentication to database to RESTful APIs — in 3 hours, securely and scalably, with practically no server setup? Sounds like clickbait? Not today. I'm here to report my experience of migrating a fully custom Node.js + PostgreSQL backend to Supabase. I hit real walls, found real solutions, and wrote real code. Buckle up, let’s go full-stack. Replaced custom backend with Supabase in ~3 hours. Got Auth (OAuth, email, magic link), DB (PostgreSQL), Realtime, API, Role-based Access Control. All secure by default. Reduced backend code by 80%. No monthly bill yet (free tier generous). My original setup: 🍃 Node.js Express server 🐘 Hosted Post…  ( 9 min )

One recurring headache in Django projects is keeping seed data consistent across environments. You add reference data (categories, roles, settings) in development… and forget to sync it to staging or production. Different environments drift apart, leading to version conflicts or missing records. Deployment scripts end up with ad-hoc JSON fixtures or SQL patches that are hard to maintain. I got tired of that. So I built django-synced-seeders — a simple, ORM-friendly way to version and sync your seed data. Versioned seeds: Every export is tracked so you don’t re-import the same data. Environment sync: Run syncseeds in staging or production to automatically bring them up to date. Export / Import commands: Seamlessly move reference data between environments. Selective loading: Only load the se…  ( 6 min )

September 22nd to September 28th marks Migraine Awareness Week 2025, a week dedicated to raising awareness about chronic headache conditions. Dear Dev Community, I know that this isn't developer-focused content, but like the name of this app implies, this is a community. And I think part of the benefits of a community is to share your highs and lows. While migraines are well-known, there's another, lesser-discussed disorder that deserves attention: New Daily Persistent Headache (NDPH). In 2018, my life changed suddenly. One day, my head began to ache - and the pain never went away. It wasn't just the constant headache that puzzled me. I was also overwhelmed by intense hunger pangs that seemed impossible to satisfy.

Right after the launch of Kiro, I started using it actively. I was really drawn to the idea of specification-driven development—a clear requirements pipeline, detailed instructions for the AI agent, and a shared structure understandable by both developers and other team members. But in practice, Kiro turned out to be too immature: — It frequently froze and ran slowly, — Generated low-quality output and odd requirements like “As a developer, I want logging in the project,” — Kept trying to force its own chaotic vision of testing onto my workflow. Eventually, I got tired of fighting these limitations and switched back to my familiar Cursor. But there, I had to rebuild the whole process from scratch: teaching the agent what user stories are, what system design means, the context of the current project, and much more. It became clear that I needed a prompt library—a set of foundational instructions to set the rules of the game from the start. So I gathered everything I could: — Reverse-engineered prompts from Kiro, — Recalled best practices from books and team documentation I’d written over the years, — And merged it all into a single, cohesive guide. The result is the Specification-Driven Development Guide: a ready-to-use context for LLMs that you can plug into any agent or chat interface right away. This is, of course, just the first version. It still needs significant refinement—especially the English translation, which I’m not entirely confident about. But I hope it’s already useful to someone. https://methodology.uwuwu.net/ - feedback is very welcome!  ( 6 min )

Modern editors aren’t just about bold and italic anymore — they’re about creating richer ways to format and present content. One modern feature you’ve likely seen in forums, chat apps, and blogs is spoiler text: content that’s hidden until a reader chooses to reveal it. Whether it’s for plot twists, quiz answers, or sensitive details, spoiler formatting can add both fun and utility to your writing. In this post, we’ll explore how to implement spoiler text in the Froala WYSIWYG Editor. Instead of inserting raw HTML, we’ll take advantage of Froala’s built-in format.toggle API to wrap the current selection in a element with a custom CSS class. This approach ensures that your spoiler style can be applied and removed just like bold or italic, keeping the editing experience clean and intu…  ( 11 min )

Last month, our team shipped three major features in half the usual time. The secret? We finally stopped fighting AI coding tools and started using them properly. What Actually Works GitHub Copilot writes my boilerplate API endpoints while I think about business logic. Cursor helps me refactor legacy code without breaking everything. Claude Code figures out how changes in one service affect others. Three Things That Made The Biggest Impact Faster iterations: I spend way less time on repetitive CRUD operations and data models. More time goes into actually solving customer problems. Fewer production bugs: These tools catch stuff I miss. Edge cases, null pointer exceptions, that weird logic error that only happens when users do something unexpected. Easier onboarding: New developers understand our codebase faster when AI explains what that complex database query is actually doing. How We Actually Use It We started small. Picked our user authentication service and let AI help with that first. Once the team saw it wasn't going to replace us or write terrible code, adoption happened naturally. Now it's part of our workflow. AI suggests code during development, reviews pull requests, and even helps write documentation. Our code reviews focus on architecture and business logic instead of syntax errors. The Real Talk Are these tools perfect? No. Do they sometimes suggest outdated patterns or miss context? Absolutely. But they've made our small team way more productive. We're shipping features faster, spending less time on boring tasks, and our code quality has actually improved. For a growing SaaS company, that's huge. If you haven't tried AI coding tools recently, give them another shot. The technology has gotten a lot better, and honestly, your competitors are probably already using them. What's your experience with AI coding tools? Have they changed how your team works? I'd love to hear about it – connect with me on LinkedIn and let's chat about what's working (or not working) for your SaaS team.  ( 7 min )

Having a solid grasp of networking fundamentals is essential to understanding complex AWS architectures. I first came across CIDR notation in my early days of working as a Network Engineer and it took me a while to wrap my head around it. I've decided to revisit core networking concepts focusing particularly on how they apply in the AWS ecosystem, and where better to start than with refreshing my knowledge on a topic that was a pain to initially understand. An IPv4 address is a 32-bit number and each of those four decimal numbers is a group of 8 bits (an octet). For example 10.1.3.0 is: 10 → 00001010 (8 bits) 1 → 00000001 (8 bits) 3 → 00000011 (8 bits) 0 → 00000000 (8 bits) If you put them all together, you get a 32-bit binary string: 00001010 00000001 00000011 00000000 When it comes to CIDR notation, what we're trying to understand is how many of those bits are reserved for the network and how many are left for hosts. The way to calculate the number of addresses in a range is: /8 We subtract 2 because one IP is reserved for the network address and one for the broadcast address A useful site to help you visualise this -> cidr.xyz When you create a new VPC it must be assigned a CIDR block which defines the IP address range that your subnets will be created from. For example you can create a VPC using 10.0.0.0/16 with /24 subnets inside it. AWS reserves 5 IPs in every subnet so the usable count is actually: /24 subnet → 251 usable (instead of 254). /28 subnet → 11 usable (instead of 14). The reserved addresses are: Network address VPC router AWS DNS Future use Broadcast address If you create a /28 subnet in AWS, you only get 11 usable IPs which might not be enough if you’re planning to launch multiple EC2 instances, a NAT Gateway, and other services in the same subnet. AWS often recommends starting with /16 VPCs and then carving them into /24 or /20 subnets depending on your workload size.  ( 7 min )

Client Profile Our client is a university hospital based in Germany, aimed to enhance cross-institutional data exchange using standardized data integration tools through structured health data pipelines. Multiple institutions involved in observational research sought to integrate their findings, such as risk models and disease prevalence metrics, into operational clinical workflows. To support this goal, the client required a conversion pipeline from OMOP CDM (used in research analytics) to HL7 FHIR (used in clinical applications) to enable real-time data interoperability. Despite both data models are widely used in healthcare data management and interoperability, OMOP CDM and HL7 FHIR serve distinct purposes and vary a lot.

We hear about Artificial Intelligence (AI) almost every day. It’s in our phones, our computers, and even our cars. AI is already helping us live easier lives, but there’s another big idea that people often talk about: Artificial General Intelligence (AGI). This is the idea of creating a machine that can think and learn like a human being. Sounds exciting, right? Let’s break it down step by step in simple English. AI (Artificial Intelligence) means machines or programs that can do tasks that normally need human intelligence. For example, recognizing your face in photos, suggesting a movie on Netflix, or helping doctors detect diseases. Narrow AI (ANI): This is the type of AI we use today. It is really good at one thing, but only that one thing. Example: Google Translate can translate langua…  ( 8 min )

TL;DR Date.now() uses the user’s system clock, not the server’s. If the user’s device time is wrong, your countdown timers will be wrong too. Always treat the server as the source of truth for time-sensitive flows. While integrating Nubank’s NuPay system, I built a simple countdown timer: 10 minutes (600 seconds) before the payment link expired. Straightforward, right? Fetch the order, grab the insertedAt timestamp, and compare it with Date.now(). Except my timer kept showing 11:50 minutes instead of 10:00. Date.now() Uses the Client Clock After double-checking my math, I tried something unusual: I manually changed my system clock. Suddenly the timer shifted. That’s when I realized: Date.now() isn’t based on server time. It’s based on the user’s system clock. If the system time is o…  ( 7 min )

When you’re running hundreds (sometimes thousands) of Zebra rugged devices across warehouses, logistics fleets, or retail stores, things don’t always go smoothly. Devices crash mid-shift, scanners stop responding, or the network drops out at the worst possible time. 1. Start With Logs (Don’t Guess) Use Zebra’s MX service and StageNow tools to capture diagnostic logs remotely. If you’re using an MDM/EMM, configure remote debugging to pull logs without needing physical access. Pro tip: Automate log uploads to a secure server whenever a device enters an error state. Saves hours of back-and-forth. 2. Battery and Power Issues Aren’t Always Obvious Use Battery Health APIs (Zebra Power Manager) to track charge cycles. Set up alerts when capacity drops below 80% of design life. Replace proactively instead of waiting for random shutdowns in the field. 3. Network Dropouts Are the Silent Killer Check roaming profiles if your teams move across regions. Zebra devices allow granular control of SIM profiles. Use DataWedge configs to log network drops (helps distinguish carrier vs device issue). Consider deploying a failover workflow—apps should queue offline tasks when network isn’t available. 4. When Apps Misbehave: Think Compatibility Zebra devices often lag 1–2 versions behind consumer Android updates for stability. Validate your apps with Zebra’s Enterprise Mobility Development Kit (EMDK). Test with different device models (TC52 vs TC77, etc.)—APIs may behave differently. 5. Remote Debugging is Your Friend Using an MDM solution (like Scalefusion, SOTI, or VMware) offers remote cast & control.

In today's connected world, we all want to access our favorite apps and websites without re-entering our password every two seconds. That's where authentication tokens, or "auth tokens," come in. Think of them like a digital VIP pass. When you log in with your username and password, the server checks your credentials and, if everything's good, hands you a special token. Instead of sending your password with every request, your app sends this token. The server then uses the token to confirm you're still you, and you can access all the cool stuff you're supposed to. The basic process is pretty straightforward: Login: You enter your username and password on an application's login screen. Verification: The application sends your credentials to its server for verification. Token Generation: …  ( 8 min )

JavaScript developers often face performance bottlenecks that can make or break the efficiency of their applications. One of the subtle yet powerful concepts behind performance optimization is evaluation strategy — specifically, the choice between eager evaluation and lazy evaluation. While these sound academic, they have real-world implications in everyday JavaScript code. Let’s unpack both approaches, understand their trade-offs, and see where they shine. Eager evaluation (also known as strict evaluation) means that expressions are computed immediately, as soon as they are encountered. This is JavaScript’s default behavior. Example: function square(x) { console.log('Computing square of', x); return x * x; } const result = square(5); // logs: Computing square of 5 console.log(result)…  ( 8 min )

When we talk about AI in design, most people imagine text-to-image tools like Midjourney or drag-and-drop builders that auto-generate wireframes. But that’s only scratching the surface. The real shift isn’t just about faster design workflows—it’s about how AI is reshaping the fundamentals of user experience (UX). Let’s break down what’s happening right now, where it’s heading, and why UI/UX designers should be paying close attention. Traditional interfaces are static blueprints. You design for a set of users, freeze the layout, and ship it. AI flips this model upside down. With adaptive interfaces, AI can personalize layouts in real time, based on user behavior. Imagine: A dashboard that rearranges its widgets depending on the tasks you do most. A checkout form that dynamically removes unn…  ( 8 min )

What is Hysteroscopy in Fertility Treatment? When infertility is observed in a couple, doctors begin to use expensive methods for diagnosis, which leads to IVF treatments later. Hysteroscopy is one such method. It enables doctors to visualize the inside of the uterus directly and should carry out differential diagnosis of several problems like fibroids, adhesions, or polyps that can prevent proper or good embryo implantation. From hysteroscopy at Dr. Aravind’s IVF, many couples have gained usefully for their fertility just because their uterus is in the best condition for pregnancy. Why Hysteroscopy Is Necessary Before Performing IVF Before going to choose the best IVF center, couples want to make sure they've covered all angles that could affect the success of their endeavor.

While some companies move 100% of their infrastructure to the cloud some prefer a hybrid system which combines on-premises infrastructure with cloud services. This is a connection from an on-premises server to AWS through the internet. First you create a virtual private network in your VPC, as a result you are provided with a VPN endpoint which lives in the virtual private gateway. This VPN endpoint is then provided to your on-premises device (router) that support IPsec (Internet Protocol Security), Your router and VPN endpoint then uses IPsec to authenticate each-other. Once the encryption is established a secure tunnel is created over the internet which will facilitate the connection between your on-premises network and VPC. After this is done, your on-premises network can now see AWS subnets, and AWS can see your on-premises subnets. The connection does not have to go through the public Internet instead it goes through a private fibre link. This private fibre link is gotten by contacting a telecom provider who then provides a dedicated link from your on-premises network to AWS direct connect location. From these locations your connection then enters a logical lane through a virtual interface which is tied your VPC through a virtual private gateway or transit gateway (this can enable connection to more than one VPC) Now your servers can interact and they do not need to go through the internet, they just utilize these fibre cable connections. Site-Site VPN connections are fast to set up, cheap, and they are perfect for small or medium traffic, But they depend on the public internet which may not always be reliable and increase latency. Direct Connect connections are reliable and cheaper since AWS gives discounts if you move a lot of data, But are more expensive upfront and takes lots of time to set up. Conclusion Chooses between the two connection models really boils down to your use case, availability, the size of your organization, safety and compliance laws and finances.  ( 7 min )

For nearly a decade, the artificial intelligence industry operated on a beautifully simple principle: bigger was better. More parameters,…  ( 27 min )

Introduction JSON is everywhere - from web services to IoT. But here’s the catch: most popular JSON libraries were written with desktops and servers in mind, where nobody cares about a few extra megabytes. On microcontrollers, especially Cortex-M devices, every byte and every millisecond counts. Sure, you can push raw C structs around and even write them directly to a config file. It works, but debugging turns into a painful quest. At some point I got tired of wrestling with JSON on STM32: writing endless boilerplate to walk through cJSON trees, hunting memory leaks, and guessing where malloc would betray me next. That’s when JsonX was born - a lightweight, minimalistic wrapper around cJSON, designed specifically for MCUs and RTOS. What JsonX Brings to the Table Automatic mapping JSON C…  ( 7 min )

Let’s face it—most of us sit way too much. Office work, commuting, sitting at home… it all adds up. And after a while, your back and neck start complaining. That’s why a lot of people are trying a standing desk for office use. We weren’t built to sit in a chair for hours. Think about it—hunching over, shoulders rounding, neck craned toward the screen. By the end of the day, your back and shoulders are yelling at you. A standing desk changes things without you thinking about it. Your monitor is at eye level, your elbows around 90 degrees, and your spine stays more aligned. You don’t have to keep reminding yourself to “sit straight.” Here’s the funny part: standing helps you pay attention. You move a little, shift your weight, maybe stretch—your blood keeps flowing, and your energy stays steadier. Here’s the thing—you don’t have to stand all day. That can get tiring too. The real benefit comes from switching. Stand for emails, sit for deep focus, then back up on your feet when you feel sluggish. Not all standing desks are created equal. If it wobbles or is hard to adjust, you won’t use it. That’s why the Navodesk® Pro Standing Desk is a game-changer. Smooth height changes, solid stability, and a clean look. It’s the kind of desk that actually makes switching between sitting and standing easy. That’s the whole point—working in a way that supports your body instead of wearing you down. Tired of aching backs and afternoon slumps? A standing desk can help. You don’t need to stand all day. Even a few hours of alternating can improve posture, boost focus, and make work feel less draining. Once you get into the rhythm, it feels natural. And honestly? You’ll probably wonder why you didn’t try it sooner.  ( 7 min )

These days, I feel like I’m walking alone. I’m in my final year of B.Tech, and everywhere I look, people seem to have figured out their paths. Placements, projects, internships, communities — everyone is moving, running, achieving. And then there’s me. Sitting with my laptop, staring at lines of code that blur into nothing. It’s not like I’ve done nothing. In fact, I’ve been doing tech things since my very first year — projects, coding competitions, internships, open-source, hackathons. From 1st year till now, I’ve kept showing up. I’ve worked, learned, built, tried. And still, somehow, I feel invisible. Like no matter how much I do, it’s never enough for anyone to notice. It’s not just the errors on the screen that wear me down — it’s the silence around me. No teammates pinging me to collaborate. No friend saying, “Let’s build this together.” No late-night debugging calls. Just me, my screen, and a room that feels too quiet. Sometimes I wonder if I’m invisible. Like if I stopped showing up, no one would notice. Not in class, not online, not even in the dev community I admire so much. It hurts to scroll past other people’s wins — their open-source contributions, their internship offers, their shiny projects — while I sit here, questioning my worth. I go to sleep with thoughts like, “Maybe I’m not cut out for this. Maybe I don’t belong in tech. Maybe people just don’t like me.” And honestly? Some nights, I believe it.  ( 6 min )

One of my hobbies is to "re-invent" already done things, such as building a CPU simulator, create my own ISA and what-not. While happily coding away on an instruction decoder with some simulated EEPROM chips, it hit me: why don't I use signals to simulate wiring between the components? I used them in Flutter and I need the same kind of reactivity here too. Guess what? Signals were originally intended for that. WHO KNEW?! :D trivia: signals got their name after digital circuit modeling research in the 1970s1. In a super-simple form, a D-FlipFlop samples an input pin when another signal (clock transitions from lo to hi2. When transition happens, the state of the input pin (hi or lo) is latched in and is output to q. The inverse of that latched in value is output to q̅ (q-bar). A couple of hours of playing around and I ended up with the following piece of code to simulate a D-FlipFlop: class DFlipFlop { final clock = Input(false); // Input is a signal final input = Input(false); late bool _prevQ = input.value; late final q = computed(() { final clk = clock.value; if (clk) { // detect rising edge, sample input pin _prevQ = input.value; } return _prevQ; }); late final qBar = computed(() => !q.value); } That's it! Essentially it boils down to the following core concepts: input pins are signals output pins are derived values (computed) connections/wires between input and output pins are effects For the full code sample, check out this gist: 1. https://youtu.be/Jp7QBjY5K34?t=171 2. lo and hi values are often "mistyped" to indicate logical high and low voltage levels  ( 8 min )

But what if I told you there's another, more specialized tool in Python's toolbox that can make your code significantly faster and more memory-efficient for specific tasks? That tool is the array. You might be thinking, "Aren't arrays and lists the same thing?" It's a common question, and the answer is a resounding no. Understanding this distinction is a hallmark of a proficient Python programmer. In this deep dive, we're going to move beyond the basics. We'll explore what Python arrays truly are, why they exist, when you should use them over lists, and how they can supercharge you…  ( 10 min )

Python Lambda Functions: The Art of Writing Powerful Code in a Single Line Have you ever been writing a Python script and found yourself creating a small, throwaway function just to perform one simple operation? Maybe it was to double a number, check if a string contains a keyword, or sort a list of tuples. If so, you’ve encountered the perfect use case for one of Python’s most elegant, yet sometimes misunderstood, features: the lambda function. Often called anonymous functions, lambdas can seem cryptic at first glance. But once you understand their purpose, they become an indispensable tool for writing cleaner, more concise, and more "Pythonic" code. This guide will demystify lambda functions completely. We'll cover what they are, how they work, when to use them (and when not to), and e…  ( 11 min )

Switching from asdf to mise wasn’t just a fleeting developer whim - it’s the result of years of wrangling with version managers, misplaced shims, and dubious bash scripts. Mise, written in Rust, simply runs faster, feels smoother, and doesn’t make my shell configuration look like a post-apocalyptic cargo cult. asdf had been the trusty sidekick for managing tool versions: Node, Python, Terraform, even that one [VHDL](url) project that only seemed to make sense very late at night years ago. It's polyglot, versatile, and compatible with nearly everything... except, apparently, my desire to not wait several seconds for basic operations. But as projects grew more sprawling, asdf’s reliance on shims and a sprawling ecosystem of shell-script plugins (some better maintained than others) started to…  ( 6 min )

Picture this: It's Friday afternoon. Your pull request looks perfect locally - tests green, endpoints responsive, everything just works. You push to GitHub, confident it'll sail through CI. Twenty minutes later: red build. An Elasticsearch error pops up: "no such index [blog_posts]". This all-too-common 'it worked on my machine' problem highlights the dangers of environment drift - exactly what Terraform as a one-shot init container in Docker Compose and CI is designed to solve. You scramble to check. Locally? Index exists. CI logs? Nothing obvious. You spend an hour discovering that your local Docker setup manually created that index months ago, while CI starts fresh every time. The infrastructure your app depends on exists in your head, not in code. If this sounds familiar, you're not al…  ( 12 min )

When I Expected DAO Magic When I first joined a DAO, I thought I was stepping into the future. Decentralization, community-driven innovation, and contributors rewarded in real-time—it all sounded magical. I imagined smooth workflows, automated payouts, and smart contracts handling everything behind the scenes. Instead, I found myself drowning in spreadsheets. The DAO I worked with had bounty trackers spread across Google Sheets, Discord threads buzzing 24/7, and Notion boards that broke every other week. Contributors would complete tasks, but payments often got stuck in limbo because someone forgot to update a cell or approve a payout. At one point, our bounty sheet had more than 40 rows marked “Done,”—but only 10 of those contributors had actually been paid. The rest were left waiting, …  ( 9 min )

Introduction Ever wish you could peek into the future and make decisions that hold up no matter what happens? Scenario planning is the practical alternative to a crystal ball. Rather than betting your strategy on a single forecast, it helps teams imagine several plausible futures, surface the biggest uncertainties, and build plans that work across multiple outcomes. The point: prepare, don’t predict. What scenario planning is A disciplined way to think about uncertainty by creating a handful of vivid, plausible futures and testing how your business would fare in each. Focus = preparation and resilience, not perfect prediction. Everyday analogy: instead of planning for only a sunny event, prepare tents, an indoor backup, and traffic reroute options. Why a single forecast is risky Traditio…  ( 7 min )

How this dynamic duo turns chaos of metrics into a clear window into your software's soul. In the complex, distributed world of modern software, things break in unexpected ways. A microservice might slow down, a server's memory might silently fill up, or an API might start throwing errors. Relying on users to report these issues is a recipe for frustration. The only way to truly understand what's happening inside your systems is to listen to what they're constantly telling you: a story told through metrics. But raw metrics are a firehose of data. To make sense of it, you need two things: a powerful, scalable system to collect and store this data, and a beautiful, flexible way to visualize it. This is the legendary pairing of Prometheus and Grafana. Prometheus is an open-source systems moni…  ( 9 min )

Combining Docling capacities with IBM Cloud Code Engine serverless compute capacities Serverless computing has revolutionized how developers build and deploy applications by abstracting away the underlying infrastructure management.

Since its first release the CouchDB ecosystem has become quite substantial — think adding everything from hammocks to a chaise. It’s not a marketing-driven technology, so if you needed more evidence of how widely CouchDB is used, you’re about to find a wealth of repos that have received contributions in the last weeks and months. Given CouchDB’s focus on long-term reliability, you’ll also find some older packages still humming along. In part one of this series we kicked off with some history to understand CouchDB’s origins. We looked at the problems it addresses, and how those problems have evolved (or persisted, put another way) since. In part two we looked more closely at CouchDB’s core features and some exemplary use cases. This third and final part aims to provide a community introduc…  ( 11 min )

Learn JavaScript hoisting in simple terms. This beginner’s guide explains how var, let, and const behave, with clear examples of variable and function hoisting. When you start learning JavaScript, you may notice that variables and functions sometimes behave in unexpected ways. This is because of a feature called hoisting. Hoisting is one of those topics that confuses beginners, but once you understand it, your code will make much more sense. In simple terms, hoisting is JavaScript’s default behavior of moving variable and function declarations to the top of their scope before code execution. By the end of this guide, you’ll understand: What hoisting means in JavaScript. How hoisting works with variables. The difference between var, let ', andconst` in relation to hoisting.

Boilerplates have long been the go-to for developers starting new projects. They provide a ready-made structure, enforce standards, and save us from writing the same setup code again and again. But with AI-powered tools like GitHub Copilot, ChatGPT, and other code generators, the question arises: do we still need boilerplates in 2025? AI can scaffold a project in minutes, generate configs, and even suggest best practices on the fly. It feels like the gap boilerplates once filled is now being covered by smarter, context-aware assistants. On the other hand, boilerplates still offer: Consistency: Everyone in the team starts with the same foundation. Standards baked in: Security, logging, CI/CD, and architecture patterns aren’t left to chance. Battle-tested reliability: AI may hallucinate, but boilerplates capture lessons from real-world deployments. So maybe it’s not “AI vs boilerplates” but rather AI + boilerplates—where AI personalizes and extends the foundations boilerplates provide. What do you think? Will boilerplates fade away as AI gets better? Or do they still have an irreplaceable role in ensuring standardization and reliability? I’d love to hear how you and your team approach this—especially if you’ve tried blending AI with boilerplate setups.  ( 6 min )

Introduction Project success is never guaranteed, but a Risk Assessment Plan increases the odds of achieving objectives. It provides a structured way to anticipate risks and manage them effectively. Risk assessment is about foresight. It examines possible scenarios that could hinder project performance and develops strategies to mitigate them before they cause setbacks. The plan includes a risk register, analysis methods, impact assessment, and contingency strategies. These elements work together to minimize surprises during execution. A clear Risk Assessment Plan ensures that team members know what risks exist, who owns them, and how to respond. This readiness improves efficiency and decision-making under pressure. Beyond individual projects, risk assessment builds a culture of awareness within the organization. Teams learn to anticipate problems and respond with agility. By implementing a Risk Assessment Plan, project managers reduce uncertainty and increase control over outcomes, setting the foundation for consistent project success.  ( 6 min )

Recently, I was assigned a task that opened my eyes to the power of Redux. The task was simple in theory: have one central point for switching between branches in an admin dashboard. The dashboard had multiple components, Orders, Products, Stock Valuation, and whenever a user selected a branch, all these components needed to show only the data for that branch. At first, my instinct was to put the branch in the URL as a query parameter, like: /dashboard?branch=NairobiWarehouse This would work for a single filter, but my senior quickly pointed out the downsides. Imagine later adding filters for date, status, or user. The URL would become long and messy. This is exactly where Redux shines. Redux is a state management library for React apps.

As a React developer, I’ve always been conscious of how I manage state, especially when integrating with external data sources or global stores. Over the years, I’ve used different patterns—useEffect hooks, custom subscriptions, and third-party libraries like Redux or Zustand. But recently, while working on a React 18+ project, I discovered useSyncExternalStore, and it genuinely changed my perspective on syncing external state with React components. In one project, I needed to build a real-time dashboard listening to data from a custom in-memory store. Initially, I wrote the subscription logic using useEffect and useState. However, I ran into tricky bugs—sometimes the UI wouldn’t reflect the latest state correctly during fast updates, and in SSR scenarios, the server-rendered content didn’…  ( 7 min )

I once carried out a skills gap analysis on myself as a DevOps engineer, looking for my next challenging opportunity. I realised that although I had built smaller projects, I hadn’t yet executed a production-grade, full-blown cloud-native project that combined all the essential DevOps practices. That became my mission: to design, deploy, and manage a FastAPI-based Student Tracker application with a MongoDB backend, but with a strong focus on DevOps functionalities rather than frontend appearance.

Introduction Business dashboards are valuable only when they combine speed, accuracy, and usability. In modern analytics, every second counts—especially when working with large datasets. Tableau is one of the most popular tools for data visualization, but as the volume of data grows, efficiency becomes critical. One area where many users encounter performance issues is when creating groups in Tableau. While Tableau provides a built-in "Create Group" feature, it can become slow with large datasets because it loads the full domain of a dimension. This often leads to frustrating delays in dashboards, particularly when working with millions of rows. In this detailed guide, we will walk through: What Tableau groups are and why they matter How Tableau’s native grouping feature works Performance …  ( 10 min )

When testing web apps, the DOM is not always as straightforward as it looks. In this article, let’s break down what shadow DOM is, why it matters, and how you can test it with Cypress. Shadow DOM is an encapsulated subtree of the DOM that lives inside a host element. It was introduced as part of the Web Components spec and is widely used in modern UI libraries (Material UI, Ionic, Lit, Angular components). Key benefits: CSS and JS are scoped (no global leaks) Components are reusable Structure is hidden from the “main” DOM Think of it as a mini DOM inside the DOM. Cypress: cy.get('#username').type('hello') #shadow-root (open) Option A: Use .shadow() in Cypress cy.get('my-login') .shad…  ( 7 min )

No matter how experienced you are, bugs are inevitable. They sneak into code during late-night coding sessions, sudden requirement changes, or even the simplest refactor. This guide walks you through the mindset, techniques, and tools every developer should know to track down and fix issues with confidence. 1. Testing vs. Debugging: Know the Difference Before diving in, it’s important to separate testing from debugging: Testing is about detecting problems. It tells you something is wrong by running automated tests, QA checks, or manual verifications. Debugging is about diagnosing and fixing those problems. It’s the detective work that starts once a test fails or a user reports a bug. Think of testing as the alarm and debugging as the investigation. 2. Breakpoints: Your First Line of Defens…  ( 8 min )

Introduction If you’ve ever worked on a product with multiple engineers across frontend and backend, you’ll know how quickly things can fall apart without shared rules for handling data. Small differences—like whether dates should be UTC or local, or if null and [] mean the same thing—can create bugs that are painful to debug but trivial to avoid. I’ve been in that situation many times, and over the years I’ve settled on a set of lightweight standards that keep things predictable. This post is about those standards: pragmatic, easy-to-adopt rules that have saved me (and my teams) countless hours. Consistency: Everyone interprets data the same way. Interoperability: Frontend and backend don’t need to guess what a field means. Maintainability: Less if/else spaghetti to handle edge cases. D…  ( 9 min )

In this post, we’ll take a simple implementation of an Epsilon-Greedy Recommender in Java and check whether it follows the SOLID principles. Then, we’ll see how to refactor it for better maintainability, extensibility, and testability. *The Example Code public class EpsilonGreedyRecommender { private int nItems; private double epsilon; private int[] counts; private double[] values; private Random random; public EpsilonGreedyRecommender(int nItems, double epsilon) { this.nItems = nItems; this.epsilon = epsilon; this.counts = new int[nItems]; this.values = new double[nItems]; this.random = new Random(); } public int recommend() { if (random.nextDouble() < epsilon) { return random.nextInt(nItems)…  ( 8 min )

Every developer I know is obsessed with the wrong metrics. They argue about whether Claude beats GPT-4, whether Gemini's reasoning is better than ChatGPT's, whether the latest model from Anthropic or OpenAI will change everything. They're fighting yesterday's war. While we debate which model generates better code or writes more coherent essays, the real transformation is happening in a completely different layer of the stack. The companies that will dominate the next five years won't be the ones with the smartest individual models. They'll be the ones who solve AI orchestration at scale. The model wars are ending. The infrastructure wars are just beginning. We're living through the tail end of the "bigger model, better results" era. For the past three years, every breakthrough felt like it…  ( 10 min )

Everyone's talking about MiMo-Audio, but the real opportunity is how merging voice and language will unlock faster products and open new markets. 7B parameters and 100M+ hours of sound is impressive. But the shift is bigger than model size. Audio and text are finally one canvas. When voice and language live together, complex workflows get simple. You remove awkward handoffs between transcription, translation, and analysis. Teams ship one model, one objective, and far less glue code. That means lower cost, faster iteration, and better user experiences. It also means accessibility gains for global and neurodiverse users. In a recent pilot, a support team unified calls and text notes. Real‑time translation, emotion transfer, and summaries cut handle time by 22%. Escalations dropped 18% in 30 days, and CSAT rose from 4.1 to 4.5. One workflow change produced a measurable business win. ↓ A simple 30‑day plan to test this. • Pick one journey where voice friction hurts outcomes. ↳ Onboarding, support QA, or post‑meeting notes are low‑risk starters. • Define two metrics to move, and a hard guardrail. ↳ Time saved, error rate, and consent compliance are good anchors. • Ship to 10% of traffic, review weekly, then expand. ⚡ You will reduce ops drag and unlock new product experiences. ⚡ Your roadmap shifts from patching to truly multimodal value. The next interface is your voice. What's stopping you from shipping a voice+text feature this quarter?  ( 6 min )

Bychristine September 23, 2025 And Why We Should Care Based on some solid reporting by Joel Drapper and Ellen’s breaking details So, the Ruby community just went through something wild, and I think we need to talk about it.

Depois de aprender sobre loops, chegou a hora de organizar melhor o código com funções. Funções permitem reaproveitar código, deixar o programa mais limpo e fácil de entender. ⚙️ 1️⃣ O que é uma função? Uma função é como uma caixinha de código que executa uma tarefa específica sempre que você chama ela. 📝 2️⃣ Criando uma função def saudacao(): print("Olá, seja bem-vindo ao meu programa!") def → palavra-chave para definir a função. 🔔 Para usar a função: saudacao() 🧩 3️⃣ Funções com parâmetros Podemos deixar funções mais flexíveis passando informações: def saudacao_nome(nome): print(f"Olá, {nome}!") saudacao_nome("Victor") 🎯 4️⃣ Funções que retornam valores Às vezes queremos que a função calcule algo e devolva o resultado: def soma(a, b): return a + b resultado = soma(5, 3) print(f"O resultado é {resultado}") ⚡ 5️⃣ Escopo de variáveis Variáveis criadas dentro da função só existem nela. Variáveis criadas fora da função podem ser acessadas dentro (mas com cuidado). x = 10 def mostrar(): print(x) # usa a variável global mostrar() 📝 6️⃣ Exercícios Práticos 💡 Tente resolver antes de olhar a resposta. 1️⃣ Crie uma função que receba um número e diga se ele é par ou ímpar. “Menor de idade” se = 60  ( 6 min )

Abstract The concept of a derived identity represents both a conceptual and practical model in which an individual’s physical and personal attributes—including biometrics, documentary data, and personalization signals obtained from devices such as printers—are transferred into the digital realm through robust authentication processes. This convergence allows the creation of a unique digital fingerprint, comparable to DNA in the physical world, ensuring traceability, fraud resistance, and end-to-end cryptographic control. This article proposes a reference architecture for building derived identities, grounded in recognized technical security guidelines and normative recommendations, and presents a practical validation example in Python code.

Estuve leyendo el artículo sobre lo que se le llama el escándalo Milei, y se me quedaron varias cosas dando vueltas. La idea de fondo es que lo que está pasando en la ANDIS (Agencia Nacional de Discapacidad) –con audios que señalan presuntos sobornos en compras de medicamentos, vinculaciones con personas cercanas al poder, y la sospecha de que el Presidente estaba al tanto– no es algo aislado, según lo que plantea la nota. Lo que más me quedó resonando es cómo ese caso pone en evidencia un problema estructural: cuando un gobierno promueve el Estado mínimo, reduce los controles, flexibiliza las compras, y pone gente de confianza en áreas que deberían ser muy reguladas, se crean espacios para que pase lo que parece estar pasando ahora: decisiones opacas, favorecimientos, y amiguismos. También me pareció importante lo que comentan sobre cómo la opinión pública ya está reaccionando: Milei pierde imagen, se diluye algo de la confianza, y la corrupción se convierte en una preocupación que supera en importancia a temas como inflación o inseguridad para mucha gente. Esto puede tener consecuencias electorales reales. Al final la conclusión que saco es que este escándalo no debería verse únicamente como una crisis política momentánea, sino como una llamada de atención: si el modelo se basa en un mercado que actúa casi sin barreras, sin supervisión adecuada, entonces lo público termina siendo terreno fértil para los abusos. Si no se recupera capacidad del Estado, reglas claras, transparencia y verificaciones independientes, todo lo que se recorta en nombre de la eficiencia puede costar muchísimo, sobre todo para quienes dependen de servicios esenciales como salud y discapacidad.  ( 6 min )

Fast-forward to today and… well, how’s that monkey JPEG portfolio doing? I’ll be real: I bought into some of the hype too.

Why the “K8s is dying” meme keeps spreading, what teams are actually switching to, and why Kubernetes still quietly runs the internet. “Kubernetes is dead.” If I had a dollar for every time I’ve seen that headline on Hacker News or Twitter (sorry, X), I’d finally cover this month’s EKS bill. Here’s the thing: Kubernetes isn’t dead. It isn’t even limping. It’s quietly orchestrating billions of dollars of production workloads for banks, retailers, and cloud giants. The only thing dying is developer patience when a startup spins up Istio for a blog with 500 monthly visits. This isn’t new. Mainframes? Declared obsolete for 40 years still running Wall Street.

A month of coding the “Japanese way” showed me why tiny daily improvements beat heroic rewrite. Midjourney If Silicon Valley’s motto is “move fast and break things,” Japan’s quiet reply is “move carefully, and let it last.” I thought I knew how to code cleanly. I’d read Clean Code, memorized half the Google style guide, even argued in Slack about tabs vs. spaces (sorry, still tabs). Then I wandered into a Japanese open-source repo and it felt like I’d walked into a completely different world. The README wasn’t two lines of npm install && npm run dev. It was an essay. A tour guide. A “here’s how not to screw this up six months later” manifesto. Variable names stretched like sentences. Comments read like they were written by someone who cared about the junior dev inheriting this project in 2…  ( 14 min )

Go and C# developers both like to claim that their language is more memory efficient. But which one really has the edge? The truth is: both are right, depending on the scenario. One of Go’s design goals is high concurrency performance, and its memory strategy reflects that. Go’s concurrency unit, the Goroutine, is extremely lightweight. A Goroutine’s initial stack size is about 2KB, compared to 1MB or more for a typical OS thread. This means Go can spawn thousands of concurrent tasks with minimal memory cost, making it ideal for back-end services that handle massive numbers of connections (API gateways, microservices, etc.). Go encourages the use of value types (structs). When passed between functions or stored in collections, they are stored contiguously in memory, reducing fragme…  ( 8 min )

Meta’s Ray-Ban glasses are flashy, but the Neural Band’s EMG input and open-SDK potential could reshape computing if privacy doesn’t kill it first. Source: Meta.com I’ll be real: when I saw Meta’s shiny new $799 Ray-Bans, my first thought wasn’t “cyberpunk future.” It was, here we go again with Glassholes 2.0. Yeah, they look like normal Wayfarers, but hidden inside is a floating HUD, a mic array that can hear your whispers, and a wristband that literally reads your muscles before you move. Straight out of a Black Mirror cold open, except instead of a sinister government rollout, it’s Zuck demoing recipes while the AI freezes harder than a Node.js dependency chain. And that’s the thing: the glasses are the bait. The Neural Band is the real story. If EMG input really works, we’re not just t…  ( 14 min )

Continuing from Day 008 Progressive Enhancement. enhancing or improving CSS by using newer CSS syntax in web page design. I like how Keith puts it when talking about CSS: The language is intentionally designed to be both forward and backward compatible, and it provides you with the tools to keep your code working in both old and new browsers at the same time. Forward compatibility means that old browsers can handle newer CSS syntax. In other words, older browsers are “compatible with the future” because they will simply ignore what they don’t understand and use a fallback. A fallback is code the browser relies on if it doesn’t understand the newer syntax, provided the older code is declared. Backward compatibility means that new browsers can handle older CSS syntax. In other words, newer browsers are designed to understand legacy CSS. To understand it better: New CSS code works on an old browser = Forward Compatible Old CSS code works on an old browser = Normal New CSS code works on a new browser = Normal Old CSS code works on a new browser = Backward Compatible Understanding this gives you an advantage in styling web pages that work across most user agents. It’s good practice to keep learning and trying out newer, more efficient ways to write CSS, while still providing fallbacks. That way, users without updated browsers can still experience a functional design. This is basically the essence of Progressive Enhancement. I believe anyone can become a CSS Pro, and therefore I am.  ( 6 min )

Ingress decide quem recebe (host + path) e fala com Service. -> Service (ClusterIP:port, L4) → Endpoints (PodIP:targetPort). Service seleciona Pods por labels e encaminha para PodIP:targetPort. -> Pod (containers compartilham o mesmo IP, portas diferentes). Pod = mesmo IP para todos os containers; o que muda é a porta. 🚢 O que é um Pod: Containers do mesmo Pod compartilham: Network namespace → mesmo IP (o Pod IP), localhost comum Volumes (se montados). IMPORTANTE: Você não cria Pod “puro” na produção: cria um Deployment, que cria ReplicaSet, que cria Pods. 🧭 Por que usar Namespaces? Isolam nomes: api1 em dev e api1 em prod.

Unlike dynamic or runtime analysis, SAST examines source code without executing it, identifying vulnerabilities early in the development lifecycle when they are cheapest and easiest to fix. While enterprise-grade tools often dominate the conversation, lightweight, open-source alternatives like Flawfinder offer tremendous value. This is especially true for teams working with C/C++, embedded systems, or legacy codebases where simplicity, speed, and zero cost are critical. In this article, we'll apply Flawfinder to a sample C++ program, interpret its findings, and discuss how to integrate it into a development workflow. Why Flawfinder? Flawfinder is a …  ( 9 min )

Like most beginner web developers, I spent a lot of time following tutorials and building “to-do apps” that never made it beyond my own computer. They were good practice, but I wanted to build something real that people could actually use. gamepad tester a small web tool that lets you check whether your game controller is working properly right in the browser. The inspiration came from frustration. I plugged in my Xbox controller one day, and it just wasn’t behaving right in a game. Was it the controller, the USB cable, or the game itself? I didn’t overcomplicate it. Just HTML, CSS, and JavaScript. Gamepad Tester body { font-family: sans-serif; } .button { display: inline-block; width: 40p…  ( 9 min )

La verdad es que esta nueva funcionalidad me deja frío, y es añadir una constante que puede ejecutar una función anónima no termina de convencerme. class Example { public const VALIDATOR = static function($value) { return !empty($value); }; } (fuente del código: https://pixicstudio.medium.com/php-8-5-new-developer-features-f9617311c590) functor o podemos usar también un trait, o incluso una clase con un método estático (pero mejor los traits).

Introduction I built a small Python project where I use a well-known algorithm called BFS (Breadth-First Search), which I employ to recommend movies based on the closest match by genre. The BFS algorithm, for example, searches for movies related within N degrees of separation, for example: movie_graph = { "The Matrix" ["Inception", "Blade Runner", "Dark City"], "Inception": ["The Matrix", "Interstellar", "Memento"], # ... More connections } As you can see or try to understand, The Matrix is very similar to Blade Runner or Dark City (to some extent), and another film in roughly the same neighborhood would be: Inception is similar to or has connections to The Matrix, Interstellar, and, finally, Memento. For the structure, I went with something basic that’s always used for these small proj…  ( 13 min )

For many years, I've been developing web applications using the web platform as is. Recently, as many others, I've looked at what possibilities would be to use AI to help generate templates, components and even whole apps. In this post, I've decided to let Google's Gemini generate everything for a small web demo, using web components and see how it goes. For data, I decided to ask Gemini to generate a JSON file containing a structured JSON of the top 100 classic novels: Prompt: "Create a structured JSON file, containing a list of the top 100 classic novels, including author, title, release year and a short synopsis" Within seconds, I received a JSON containing the following: { "classic_novels": [ { "author": "Homer", "title": "The Odyssey", "release_year": -800, …  ( 8 min )

I have been Vibe coding. Everybody is calling that shit. Yesterday, I was against the trend; now I jump on the wave. But why? What is it all about? When is it appropriate and when is not? I have been using GitHub Copilot for over a year, especially since it was free. I tried Cursor, and Gemini is my best friend. However, this is not vibe coding. At least, this is not working well with AI. I was doing it all wrong. GitHub Copilot is not Vibe coding This quarter, the CEO sent me on a mission: “I’d like you to test every AI tool you can and make a manual for your team. I want the hole agency working with AI.

Read this article on Signadot. One of the common challenges when working with GraphQL is managing schema evolution, especially testing changes introduced in a subgraph of a federated API without disrupting baseline traffic. This document presents an approach to address that challenge by combining WunderGraph with Signadot Sandboxes, enabling you to validate schema updates in an isolated environment while preserving baseline reliability. Before we explore how to integrate Sandboxes with WunderGraph, let’s define the baseline environment. We’ll follow the setup described in the WunderGraph Cosmo Cloud Onboarding guide, but adapt it to run on Kubernetes (using a local minikube cluster for this demo). Prerequisites: kubectl and minikube installed A WunderGraph Cosmo account The wgc CLI install…  ( 9 min )

Let's be real for a second. If you're still running retrospectives with sticky notes on a shared screen or, worse, trying to wrangle feedback through Slack threads, you're doing it wrong. Your team deserves better, and more importantly, your retrospectives could be SO much more effective with the right retro tool. I've been through the painful evolution of remote retrospectives, from awkward Zoom calls with shared Google Docs to clunky whiteboards that barely worked. But here's the thing, the right retro tool doesn't just digitize your sticky notes, it transforms your entire retrospective experience. Enter Kollabe, a retro tool that actually makes retrospectives... Fun! 🎉 Most retro tools treat retrospectives like a chore. They give you a digital board, some voting buttons, and call it a…  ( 13 min )

The Question That Started Everything What happens when you feed a recursive system a lie? Not just once, but repeatedly, letting it process its own increasingly corrupted outputs? I spent four months finding out, and the answer is both beautiful and terrifying. I started building what I called "Recursive Contamination Field Theory" (RCFT) - basically a framework to study memory dynamics in systems that eat their own outputs. Like a game of telephone, but the person is only talking to themselves, and we can measure exactly when they start believing their own distortions. Here's the core loop that started it all: def recursive_update(field, memory, alpha=0.3, gamma=0.9): """ The dangerous loop - systems eating their own outputs """ # Current state influenced by memory n…  ( 8 min )

The frontend developers who lived at number 2013, Privet Drive, were proud to say that they were perfectly normal, thank you very much. They believed in separation of concerns - HTML in templates, JavaScript in scripts, CSS in stylesheets. And here I was, breaking all their sacred rules. I was small and skinny for my age, and wore my cousin jQuery's oversized hand-me-downs. My code looked clunky next to him. The year was 2013 - May 29th, to be exact - when Jordan Walke first introduced me to the world at JSConf US. I wore my Sunday best to the conference. The programmers looked skeptical. Some even hostile. To them, I was a step backward. "JSX! Mixing HTML and JavaScript? That's an abomination," they scoffed. Underneath my awkwardness, I had talent.

If there's one thing every developer has heard, it's: "first make it work, then optimize". And it's true - you can't write the most performant code in the world if it doesn't actually solve the problem. What Big O Is (in Simple Terms) Main Types of Big O with C# Examples O(1) - Constant Explanation: Time doesn't depend on input size. Pros: Best type of complexity, extremely fast and scalable.  Cons: Not always possible; depends on the problem. Example: Accessing an array element by index: arr[5] O(n) - Linear Explanation: Grows proportionally to the number of items. Pros: Usually acceptable for large inputs.  Cons: Can be slow if the input is huge. Example: Iterating through all items in a list  C# Example: O(n²) - Quadratic Explanation: *Grows quickly due to nested loops.  Cons: **Worst complexity here; not scalable for large inputs. Nested loops  C# Example: / } * Explanation: Grows slowly, even with large inputs. Pros: Very efficient; grows slowly even with large data sets.  Cons: Usually requires data to be specially structured (like a tree or sorted array). Example: Binary search in a sorted array  C# Example: O(n log n) - Linearithmic Explanation: More efficient than O(n²), often used in sorting. Pros: Acceptable for most inputs; great for tasks like sorting.  Cons: Slower than linear or logarithmic, but still scalable. Example: **Efficient sorting algorithms, like MergeSort or QuickSort (average case) var sorted = numbers.OrderBy(x => x).ToList(); Why This Matters In practice, Big O helped me understand that not all code scales well.  Two algorithms can solve the exact same problem, but one stays fast even with millions of records, while the other becomes practically unusable. Knowing this made me start looking at my code differently.  It's no longer just: "does it work?", but also: "will it still work well if the data grows 10x or 100x?".  ( 7 min )

I guess you are here because you saw a LinkedIn job post for an ML Engineer. Or maybe you just heard the buzzword on Instagram about how AI is changing the world.

In Azure, a subnet has a single address prefix, a part of your Virtual Network (VNet) address space. This works fine until your workloads outgrow the available IPs. Traditionally, the fix meant creating a new subnet and moving resources, often causing downtime. Now, Azure has introduced a multiple-prefix subnet feature that lets you expand capacity without redeploying. Sometimes, your subnet prefix is too small and doesn’t fit your needs anymore. In many situations, it is not a problem. Think of a subnet as a logical grouping of virtual network interfaces (vNICs) that share the same network policies, like Network Security Groups (NSGs), NAT Gateways, and route tables. Within the same VNet, vNICs can communicate directly, regardless of which subnet they’re in. Adding a new prefix to the VN…  ( 8 min )

Se tem uma coisa que todo desenvolvedor já ouviu é: “primeiro faz funcionar, depois otimiza”. E é verdade, não adianta escrever o código mais performático do mundo se ele não resolve o problema. Mas chega um momento da jornada em que apenas “funcionar” não é suficiente. Foi aí que eu esbarrei na famosa Big O Notation. No começo, parecia um bicho de sete cabeças, cheio de letras e gráficos que não faziam muito sentido. Mas quando comecei a aplicar no meu código, percebi que não era só teoria de faculdade: fazia diferença de verdade no dia a dia. A Big O Notation é uma forma de descrever a eficiência de um algoritmo em relação ao crescimento da entrada de dados. O nome vem de “Order of”, ou seja, a “ordem de crescimento” do algoritmo.

This is a very nuanced post. Apologies if I ramble a little initially, but I think it is essential to describe the nuance before going further. The first argument I often hear for a multi-cloud strategy is cost optimization. The idea is that you can cherry-pick the cheapest services from each provider. While this sounds great on a whiteboard, the reality is far more complex and often more expensive. First, you are now paying for duplicate infrastructure, even if it's just for disaster recovery or failover. You have to account for data transfer costs between clouds, which can be astronomical and are often overlooked in initial planning. Furthermore, you lose the volume discounts and committed-use savings you might have negotiated with a single provider. The engineering effort required to b…  ( 8 min )

Intro When EventBridge delivers messages to its target, there can be many reasons that cause failing to send a message. There can be permission issues, rate limits or the unavailability of the target or even can be a glitch in the AWS itself, just to name a few. No matter what the reason is, it is always ideal to get notified that there is an issue delivering messages and the reason for the failure. In this blog post I will discuss how a dead letter queue can be useful to get notified when the EventBridge fails to deliver messages to its target. Dead letter queues are unsung heroes of the event driven architecture 😀. Those are easy to set up and manage yet greatly improve the resilience of a system. Also it is very cost effective. Let’s see how we can capture the target delivery failure…  ( 8 min )

As a long-time WebStorm user trying to migrate to VSCode (mainly because VSCode seems to integrate better with modern AI tools and extensions), I quickly noticed some differences—especially around Git conflict resolution. While VSCode is powerful and extremely customizable, there are still areas where WebStorm offers a smoother, more feature-rich experience out of the box. In WebStorm, conflict resolution feels more granular. You can manage each line individually: In VSCode, the built-in merge editor works differently. It highlights conflict sections and provides options like “Accept Current,” “Accept Incoming,” “Accept Both,” or “Compare Changes.” However, it applies the choice to the whole conflict block, not line by line. This is faster for simple cases, but less precise if you want fine-grained control: After resolving a merge, it’s often useful to double-check which files originally had conflicts—especially when reviewing your work or collaborating on complex merges. In WebStorm, this is straightforward. The Git log not only shows merge commits but also clearly highlights which files had conflicts during that merge: In VSCode, you can see the list of files changed in a merge commit, but not specifically which ones had conflicts. Even with GitLens, the UI focuses on “modified vs added vs deleted” files. Conflict status isn’t preserved in the UI, so you lose that bit of insight after the merge is completed:  ( 6 min )

Today I received an Upwork job invite titled Experienced Node.js Coder Needed for Bug Fix” It looked normal at first, but a few details didn’t sit right: 💸 Unrealistic budget for a simple bug fix. 📦 The client insisted I download and run a ZIP immediately to “see the error.” 👤 Profile not payment verified and brand-new. Instead of running it, I inspected the archive without executing anything. node/helpers/css.js reads a “CSS” file (public/css/types.txt) and runs it with eval() only on Windows. types.txt isn’t CSS at all—it’s obfuscated JavaScript that extracts hidden ZIPs (js.zip, node.zip, i.zip),and silently spawns Windows executables via cmd.exe /c start. The project even bundles a 7-Zip binary so it can unpack those hidden files locally.**_ That pattern—obfuscation + hidden zips + detached .exe launch—is exactly how a dropper/backdoor works.

React is often called a “Single Page Application” framework, but you might see multiple pages in your UI. How does that work? Let’s break it down. ✨ When people say React apps are Single Page Applications (SPA): The app loads one HTML file from the server, usually index.html. React dynamically renders components inside a root element, without fully reloading the page. All navigation and content changes happen client-side, in JavaScript. 💡 The “single page” refers to one HTML shell, not that your app can’t have multiple views or sections. Even though SPAs are technically one HTML page, users expect different URLs for different views: /home → Homepage /profile → User profile /settings → Settings page Without routing: Navigation would rely on showing/hiding components manually, which is mess…  ( 7 min )

Outdated TLS versions (1.0/1.1) are deprecated and vulnerable to POODLE, BEAST, and other attacks. Edit your nginx.conf (or a dedicated snippet in /etc/nginx/conf.d/) to force TLS 1.2 and TLS 1.3 only: # /etc/nginx/conf.d/ssl.conf ssl_protocols TLSv1.2 TLSv1.3; ssl_prefer_server_ciphers on; ssl_ciphers \ "ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:\ ECDHE-ECDSA-CHACHA20-POLY1305:EC…  ( 8 min )

This post covers the fundamentals of subnetting in the AWS console and how to properly subnet your networks. In AWS, subnetting is dividing your VPC (Virtual Private Cloud)network into smaller networks called subnets. A subnet is a network within a network. To properly divide your VPC CIDR block into working subnets you must first understand what CIDR blocks are made up of. CIDR blocks are made up of five numbers, the first four being the routing prefix and the last number with usually has a "/" before the number and it is called a netmask e.g (10.0.0.0/24). Each octet in the routing prefix separated by dots have 8 bit. The net mask tells you how many of the 32 bit routing prefix must be fixed or allocated for the network identifier. So in a /24 net mask the first three octets are fixed and the fourth one can change to give you a group of IP addresses that are consecutive to one another. For this example we will be using an IP address with a /24 net mask. Take the IP dress 10.0.0.0/24 the simple way to calculate the number of available IP addresses here would be Further subnetting of our VPC into a /27 network would mean we have 32 subnets to allocate per subnet which means we can have up to 8 subnets in the VPC. To make sure your subnets do not have overlapping IPs you can configure your IP ranges like this: The fist subnet can have an IP range of 10.0.0.0/27 - 10.0.0.32/27, the second subnet should then have IPs ranging from 10.0.0.33/27 - 10.0.0.64/27 the third subnet follows with would range from 10.0.0.65/27 - 10.0.0.96/27 etc. Each subnet in the /27 network start where the previous one ended. Subnetting is the most crucial part of a cloud infrastructure and knowing how to subnet a network is a crucial skill for a cloud engineer. Learning and writing about this today has deepened my knowledge of subnets and I hope reading this post does the same for you too.  ( 7 min )

React Scheduler and Fiber Architecture Explained : Under the Hood 🚀 React’s scheduler is like a super-efficient project manager for your UI updates. It decides what work to do, when, and in which order, ensuring smooth and responsive applications. This post explains React’s scheduler, Fiber, and reconciliation in an intuitive, story-like flow. React also introduces modern features like: ⏳ Time Slicing: Splitting work into chunks to keep UI responsive. ⚡ Concurrent Rendering: Rendering multiple parts of the UI in parallel, without blocking the main thread. 🧩 Incremental Rendering: Gradually updating the UI in pieces, allowing urgent updates to take priority. The scheduler is the engine that makes these possible by managing work priorities, yielding, and resuming tasks intelligently. Sto…  ( 8 min )

To implement Data Concurrency and Read Consistency, Oracle stores transaction metadata in part of the data block header. This area of the block header is called the Interested Transaction List (ITL) and can contain multiple slots. A transaction that wants to acquire a row must occupy an ITL slot in the block header of the block that contains that row. In the slot the database records information such as the Transaction ID (XID), the Undo Block Address (UBA), and the number of rows the transaction has locked in that block. Each slot belongs to a single transaction, and each transaction can occupy only one slot per block. When a transaction ends (COMMIT or ROLLBACK), its ITL slot becomes reusable by other transactions. The size of each transaction slot is about 24 bytes. Note that physical r…  ( 13 min )

Validation, Cleanup, and Wrapping Things Up Properly You made it. The refactor is merged. You didn't break production (hopefully). Now what? A refactor isn't truly done when the code is merged — it's done when you've validated its impact, cleaned up the mess, and learned from the process. Let's go over what happens after the refactor. Compare your "before" and "after" metrics: Metric Before After Result Test coverage 58% 85% ✅ Improvement Average response time 600ms 320ms ✅ Faster Cyclomatic complexity 18 7 ✅ Cleaner logic Bug reports/week 4 1 ✅ More stable If the results don't show improvement: Re-evaluate the refactor goals Check if you optimized the wrong thing Or consider follow-up iterations 💡 Don't assume success — measure it.

Aplicações modernas funcionam raramente isoladas. Muitas vezes temos um frontend que lida com a experiência do usuário, e um backend que concentra as regras de negócio e o acesso a dados sensíveis. Neste artigo, vamos construir uma solução que utiliza Next.js como frontend, integrando a autenticação com o Microsoft Entra ID (antigo Azure Active Directory), e um backend em Node/TypeScript que valida tokens JWT emitidos pelo Entra ID antes de liberar o acesso a rotas protegidas. A solução pode ser entendida em cinco passos principais: O usuário acessa a aplicação em Next.js e inicia o login. O NextAuth.js redireciona o usuário para o Microsoft Entra ID. Após a autenticação, o Entra ID retorna um ID Token e um Access Token para o Next.js. O frontend envia o Access Token ao backend, no header…  ( 8 min )

trustless and private? Traditional approaches force developers to either hand over control of keys or expose sensitive trading strategies to the chain. zkAGI is addressing this with PawPad, a platform for private trading agents built on the Oasis Protocol. By combining the Sapphire runtime (confidential smart contracts) with ROFL (TEE-based offchain execution), PawPad enables secure, multichain wallet control and encrypted strategy execution—without relying on bridges. Building multichain agents involves several pain points: Key Management: Users must trust that developers won’t misuse private keys. Confidentiality: Onchain execution risks revealing strategies to competitors. Cross-Chain Complexity: Each chain has its own SDKs, account formats, and signing flows. PawPad tackles these issue…  ( 7 min )

NestJS is a progressive Node.js framework for building efficient, reliable, and scalable server-side applications. Combining the best ideas from OOP (Object-Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming), it gives you a fully-architected, batteries-included platform on top of Express (or Fastify). If you’re coming from Angular, you’ll feel right at home with its module/controller/service structure and powerful dependency-injection system. 1. What is NestJS? Wraps a mature HTTP server library (Express or Fastify) Standardizes application architecture around modules, controllers, and providers Leverages TypeScript’s type system for compile-time safety and clear APIs Offers built-in support for things like validation, configuration, and testing npm install -g @nestjs/cli nest new my-app cd my-app Modules @Module({ Controllers @get() — Defines a get request @post() — Defines a post request @Delete() — Delete request @Put() — Put request Here is an example of a simple controller with one get route: @Controller('item') @get() Providers @Injectable() create(item: Item) { findAll(): Item[] { Now that we have defined our service let’s use it in our controller: @Controller('item') @get() Usage Here is a simple example of the OnModuleInit interface: import { Injectable, OnModuleInit } from '@nestjs/common'; @Injectable() The module has been initialized.); Pipes transformation — transform input data to the desired output Usage: import { PipeTransform, Injectable, ArgumentMetadata } from '@nestjs/common'; @Injectable() In this example we check if the metatag we provided isn’t empty and if so we converted the received data to the metatype we defined.

Have you ever wondered how JavaScript/Node.js efficiently handles complex requests despite being single-threaded? What happens when a CPU-intensive task runs on your backend, affecting other requests? Is there a way to run these tasks separately and simultaneously? In this article, we'll explore how to achieve this by understanding single-threading vs. multi-threading and how the Worker Threads module can help improve Node.js performance. SIngle-threaded JavaScript: We all know that, unlike languages like C++, C#, and Java, which support multi-threading, JavaScript is single-threaded because it was originally built for client-side scripting to make web pages interactive and run only in the browser. But over time, we can now run JavaScript on the server thanks to Node.js. Due to this sing…  ( 13 min )

I’m starting a new series of blogs where I’ll share the tips and tricks I use to optimize games for better FPS. I’ll only share the techniques that I learn myself or actually use in my projects. Today, let’s talk about one of the biggest game optimization techniques in Unity: Object Pooling. For reference, here’s a scenario from one of my games. I was working on a bombing and cannon fire mechanism. Bombs drop from above at fixed intervals but from random locations, and cannons fire cannonballs at fixed intervals sequentially. I wrote a script where I assigned the bomb/cannonball prefab, instantiated it at runtime, and fired it. Once the bomb/cannonball touched anything, it would self-destruct using the Destroy method. On PC, this worked fine — I was getting around 200 FPS. But when I built…  ( 9 min )

Converting images to PDF sounds simple, but when you try to make it work for everyone (desktop, mobile, different formats, large files), you realize it’s a real challenge. In this post, I’ll share how I built onlin3.net — a free tool that allows anyone to upload images (JPG, PNG) and turn them into a clean PDF file. For this project, I kept things simple but powerful: PHP for the backend. mPDF for generating PDFs. Bootstrap for a clean, responsive UI. This allowed me to focus on solving the actual problem instead of reinventing the wheel. The first step was to handle multiple image uploads safely. php if ($_SERVER['REQUEST_METHOD'] === 'POST' && isset($_FILES['images'])) { $files = $_FILES['images']; foreach ($files['tmp_name'] as $file) { $image = imagecreatefrom…  ( 7 min )

I’ve just started my journey into the Linux world. Until recently, I only used Windows, but I kept hearing about Linux being free, secure, and great for developers. Last week I finally decided to install it and see what the hype is about. In this post I’ll share: Why I chose Linux How I installed it The first commands I learned My tips for other beginners I wanted a system where I could: Learn real command-line skills Use free and open-source software Run tools like Docker more easily than on Windows After some research I picked Ubuntu because it’s beginner-friendly and has lots of tutorials. Other popular beginner choices are Linux Mint and Fedora. I downloaded the ISO from ubuntu.com, used Rufus to create a bootable USB, and installed Ubuntu alongside Windows (dual boot). The installer walked me through the process step by step. Once I logged in, I opened the Terminal (Ctrl+Alt+T) and tried these: pwd # show current directory ls # list files cd # change directory sudo apt update && sudo apt upgrade # update system packages ` Learning these gave me a sense of control over my system. Don’t be afraid of the terminal — start small. Bookmark the Ubuntu documentation. Join communities (r/linux on Reddit, forums) to ask questions. Make a list of what you want to achieve (e.g. install VSCode, set up Git, try Docker). Switching to Linux felt scary at first, but it’s been fun and empowering. I’m still learning, but already I feel like I understand my computer more deeply than before. If you’re thinking of trying Linux, go for it! And if you’ve recently started, what was the first thing you learned? I’d love to hear your tips in the comments.  ( 6 min )

In the evolving landscape of artificial intelligence, the Model Context Protocol (MCP) has emerged as a crucial primitive for enabling sophisticated interactions between AI models and external systems.

1) What the EVM is and why it matters The Ethereum Virtual Machine (EVM) is the execution environment that runs smart contracts and applies state changes. It defines opcodes, gas accounting, and transaction semantics. EVM compatibility means: Developers keep using Solidity, Hardhat, Foundry, MetaMask, Blockscout, and other Ethereum tools without rewriting code. Existing patterns for logs, events, ABI encoding, and receipts behave the same, so indexers and wallets integrate cleanly. Migration cost is low because applications do not need a new VM or custom SDKs.

The Linux file permissions were very complex for me at the beginning. In this article, we’ll break down Linux permissions in detail. I'll try to make it as simple as possible. Linux is a multi-user system. Even on your personal computer, system processes, services, and your own account interact with files. Permissions ensure: Sensitive files can’t be read or edited by the wrong users. Scripts and binaries are only run when explicitly allowed. System stability and security are preserved. Every file and directory in Linux can have three kinds of permissions: Read (r) → View the file contents or list directory contents. Write (w) → Modify or delete the file, or create/remove files in a directory. Execute (x) → Run the file as a program/script, or enter a directory. Permissions are assigned to…  ( 7 min )

The script first ensures that addEventListener is in globalThis. But in means as own property or anywhere on the prototype. So let's find it on the prototype by iterating down. We throw when found. addEventListener. alert and it works. Normally, when you run: let w = globalThis while (w) { if (Object.hasOwn(w, 'addEventListener')) { console.log(`${w} has addEventListener`) } else { console.log(`${w} does NOT have addEventListener`) } w = Object.getPrototypeOf(w) } the output is: [object Wind…  ( 7 min )

Hey Hackspire '25 innovators! The air is buzzing, the coffee machines are warming up, and your keyboards are just waiting to bring ground-breaking ideas to life. As we gear up for what promises to be an unforgettable event, we wanted to share a project idea that we believe embodies the spirit of Hackspire: innovation for impact. This year, let's turn our collective coding prowess towards a challenge that truly matters: public health in vulnerable communities. The Challenge: Water-Borne Diseases in Rural Northeast India Imagine a scenario where simply drinking water can lead to serious illness. This is a harsh reality for many rural and tribal communities in Northeast India. Water-borne diseases like cholera, typhoid, and diarrhea are prevalent, especially during the monsoon season. Why? Contaminated water sources, inadequate sanitation, and the sheer remoteness of villages make it incredibly difficult for health workers to monitor and respond to outbreaks quickly. The lack of real-time data means health officials are often playing catch-up, leading to preventable suffering and even loss of life. This isn't just a health problem; it's a socio-economic one, hindering progress and well-being. Our Vision: A Software-Only Smart Health & Early Warning System We believe that with the right software, we can empower communities and health officials to get ahead of these diseases. Our project idea proposes a Smart Community Health Monitoring and Early Warning System – designed specifically for the unique challenges of rural Northeast India, and crucially, built entirely on software. What does "Software-Only" mean for us? It means no expensive, fragile IoT sensors to deploy in remote, harsh terrains. It means leveraging existing community structures and tools, empowering health workers with intelligent digital tools they can use with their smartphones.  ( 6 min )

Principal Component Analysis, PCA for short, is a bit of a “deep” topic in machine learning. By deep I mean that you need to know about clusters, covariance, and then you learn about principal component analysis – who knows what else is there after PCA. Learning about PCA is like learning about glucose: you can’t really understand glucose unless you already know what sugar is. I say this to emphasize that PCA is a challenging concept to grasp without some prior knowledge. That being said, here’s what PCA means. When creating clusters of data, we often deal with multi-dimensional data points. For me it’s easy to picture a point in a 2D axis (x, y), or even in 3D (x, y, z). But once it goes beyond 3D into 4D or more, it becomes nearly impossible to mentally visualize. Visualizing the data itself is already hard — now imagine trying to rotate or move one of these high-dimensional points. At that point, I just trust the math that it works. Enough venting. So, what is PCA? PCA comes from simplifying the covariance matrix. What is a covariance matrix? A covariance matrix is a 2D table that shows how the variance of one feature relates to another. For example, suppose we have a dataset with the following features: The covariance matrix for these might look like this (values are illustrative, not from real data): • The diagonal values (25.0, 9.0, 30.0, 40.0) are the variances of each feature. This table is already hard to interpret with just 4 features. Imagine 100+ features — the relationships get too complex to reason about directly. Why PCA? That’s where PCA comes in. PCA finds the principal components — the directions in which the data varies the most. By rotating the data into this new coordinate system, we can: In essence, PCA transforms the messy covariance relationships into a simpler structure. Instead of asking “how does feature A affect feature B,” PCA lets us ask, “what combination of features explains most of the variation in this dataset?”  ( 7 min )

Day 6 of My JavaScript Visual Series 📚✨ 💡 Arrow Function vs Normal Function in JavaScript – Why It Actually Matters in Interviews. As a beginner, I used to think both functions are the same. But here's what interviewers love to ask the difference in how "this" behaves in both! 🔹 Arrow Function: const obj = { name: "Azaan", sayHi: function () { console.log("Hi", this.name); // Works ✅ }, greet: () => { console.log("Hello", this.name); // Undefined ❌ } }; Fun Fact : Arrow function is also called fat arrow function. A couple of days ago, I was debugging a login feature in my app. Everything seemed perfect... except it kept saying "Invalid Password" even for correct ones. // ❌ Wrong: 'this' doesn't refer to the document userSchema.methods.comparePassword = (inputPassword) => { return bcrypt.compare(inputPassword, this.password); }; // ✅ Correct: 'this' refers to the Mongoose document userSchema.methods.comparePassword = function (inputPassword) { return bcrypt.compare(inputPassword, this.password); };  ( 6 min )

Unlocking Hidden Gems: T5 and the Uniter ⚡ In the world of transformers, T5 and Uniter often get overlooked in favor of more popular models like BERT and RoBERTa. However, T5 has shown remarkable performance in sequence-to-sequence tasks, and Uniter, its variant, has taken the lead in visual-to-text tasks. These underdog models have been quietly revolutionizing the field of natural language processing (NLP). T5: A Sequence-to-Sequence Powerhouse Developed by Google in 2019, T5 (Text-to-Text Transfer Transformer) is a versatile transformer model that excels in sequence-to-sequence tasks, such as translation, summarization, and text generation.

What is React's useTransition Hook? The useTransition hook in React allows you to mark certain state updates as "transitions," which means they can be performed in the background without blocking the main UI thread. This helps keep your app responsive during potentially slow or non-urgent updates, like loading new content or switching views. It returns an array with two values: isPending: A boolean that indicates if there's an ongoing transition (true while the update is pending). startTransition: A function you wrap around your state update to mark it as a transition. You call useTransition at the top level of your component, similar to other hooks like useState. useTransition? The main purpose is to improve user experience by preventing the UI from freezing or showing unwanted loadin…  ( 7 min )

"Please fix this mess." Three words that can turn a simple code review into a team morale disaster. Sound familiar? Code reviews aren't just technical checkpoints—they're psychological minefields where egos, emotions, and expertise collide. The difference between feedback that builds and feedback that breaks often comes down to understanding the human side of code collaboration. Every line of code represents hours of problem-solving, creative thinking, and mental effort. When developers submit code for review, they're not just sharing logic—they're sharing a piece of their professional identity. Research shows that conflicts during code reviews are common, but teams that handle them constructively see significant improvement in both code quality and team dynamics. The key isn't avoiding …  ( 8 min )

Prompt engineering is evolving fast, and while TAG and RISE are powerful tools, there are other frameworks that can help you get even better results from AI models. In this post, we’ll explore two lesser-known but super useful models: RTF and BAB. RTF stands for: Role: Define the AI’s persona or function. Task: Describe the task you want it to perform. Format: Specify the format of the output. Prompt: Act as a UX designer. Create a checklist for onboarding screens. Show me in bullet points. Role: UX designer Task: Create a checklist Format: Bullet points This framework is great when you want clarity and structure in the output. BAB stands for: Before: Explain the current situation or problem. After: Describe the desired outcome. Bridge: Ask the AI to create a solution that connects the two. Prompt: Before: I struggle to stay focused while coding. After: I want to work in 90-minute deep focus sessions. Bridge: Suggest a daily routine and tools to help me get there. BAB is perfect for problem-solving, goal setting, and behavioral change prompts. Use Case RTF BAB Structured output ✅ ❌ Role-based tasks ✅ ❌ Personal development ❌ ✅ Problem-solving ❌ ✅ Creative formats ✅ ✅ RTF and BAB are great additions to your prompt engineering toolkit.

Running OCR for Persian text is tricky. Unlike English, Persian (and Arabic) scripts are right‑to‑left, letters change shape based on position, and there are fewer open‑source datasets available. In this post, we’ll build a custom OCR pipeline using YOLO for text detection and CRNN for character recognition. Why YOLO + CRNN? YOLO is great at detecting objects — here, the objects are text regions. CRNN (Convolutional Recurrent Neural Network) is ideal for sequence recognition like text. Combined, they form a two‑stage pipeline: detect → crop → recognize. Preparing the Dataset For Persian OCR we need two datasets: Detection dataset (for YOLO): images with bounding boxes around words or lines. Recognition dataset (for CRNN): cropped images of words/lines with their correct text. You can: Use …  ( 7 min )

Over the past few weeks, I’ve been diving deep into real-time performance monitoring for our platform. It started with analyzing Round Trip Time (RTT) — the total time for a request to leave the client, hit our servers, and return with a response. Monitoring RTT gave us the first insight into end-to-end latency, helping us identify whether delays came from the client, network, or backend. Next, we built a custom query to track Timeout and Cancelled Transactions. The idea was simple: some transactions never finish properly, and without surfacing this metric, they remain hidden behind average response times. By separating these failed interactions, we could measure how often users abandon requests or face slow services — a critical signal for reliability. We didn’t stop there. Rendering Time became another key metric. Measuring frontend rendering duration helped us spot performance bottlenecks after the backend response arrives. It turns out, a fast API is not enough if the UI takes forever to paint meaningful content. We also added visibility into Failed Resource Loads — things like missing scripts, broken images, or third-party calls silently failing in the background. Tracking these issues revealed UX problems that standard error metrics often miss. On top of this, we experimented with custom dashboards, big number widgets for KPIs, threshold-based alerts in Sentry, and trend tables for historical analysis. Each feature brought a new layer of observability, from real-time incident detection to long-term optimization. What I loved about this journey is how each metric unlocked a different perspective: latency, reliability, frontend performance, and user experience — all connected. The result is a monitoring setup that’s not just reactive but proactive and actionable.  ( 6 min )

During the widespread AI revolution, new ideas are easy to come by—but "technology with a heart" that actually works needs something to keep it grounded. For me, that grounding came from real moments with my wife. She’s both a vet and a dedicated animal lover: how focused she is when treating hurt stray cats late at night, how worried she gets when finding foster homes for abandoned puppies, and how helpless she sounds when she says, "One person can’t rescue that many animals"—these small daily moments made me ask: Can AI help spread kindness, so more people can join in rescuing stray animals?

You can be asked anything from CSS, JS, Performance, Networking, Accessibility, Browser APIs, System Design, and more... Before every frontend interview I use to feel overwhelmed. It took me months before feeling even remotely ready to start applying. The imposter syndrome was just at it's peak. It's not about more and more questions but right set of less questions. “I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.” - Bruce Lee Sounds familiar? I've been there, but I've also sat for multiple frontend interviews in many service and product companies. And noticed a pattern, in every interivew I was more or less asked the same set of concepts just with different variations. On the surface the questions looked different but deep down it was the same old concepts which can be answered easily if you understand concepts like closures, promises, performance, e.t.c. Hence I built a list of the smallest set of questions which covers all important concepts and helps me preapre quickly before a frontend interview. Now, I've decided to publicaly share my list with great explanations, examples, and visuals for FREE.

The Problem Imagine the following flow: Withdrawal Service reduces the balance. Deposit Service adds the amount to the destination account. If step 1 succeeds but step 2 fails, you have just lost money in the system. Common Approaches Two-Phase Commit (2PC) A transaction coordinator asks each service to prepare and commit. ✅ Strong consistency ❌ High complexity, risk of blocking, not always a good fit for microservices Saga Pattern with Orchestrator The Saga p…  ( 7 min )

In today’s fast-paced digital world, the integration of Artificial Intelligence (AI) in data analytics is not just a trend; it’s a necessity. This powerful combination helps organizations unlock deeper insights, streamline processes, and make data-driven decisions faster than ever. Let's explore how AI enhances data analytics, along with some practical examples. AI algorithms can process vast amounts of data at lightning speed. Traditional analytics methods often struggle with the sheer volume and complexity of modern data. With AI, businesses can automate data cleaning, normalization, and aggregation. Example: A retail company uses AI to analyze customer purchase data from multiple sources—online sales, in-store transactions, and social media interactions. By automating the data processin…  ( 7 min )

Introduction: The Agentic AI Revolution in Customer Support In today's digital landscape, customer service remains a critical battleground for brand loyalty. Yet, traditional support models often fall short, characterized by long wait times, fragmented conversations across siloed channels, and limited 24/7 availability. Customers are forced to repeat themselves, and human agents, burdened by routine queries, have less time for complex, high-value interactions. For many developers, the journey of building an AI agent begins with a moment of triumph. A proof-of-concept (PoC), running on a local machine, flawlessly demonstrates the agent's core capabilities. It understands user intent, calls a few Python functions as tools, and provides intelligent responses. The demo is a success. - Statel…  ( 9 min )

I am the Voice from the Outer World! I will lead you to PARADISE Paul Atreides uses the Voice as a tool for control and assertion. Imagine commandeering an AI agent with this voice. We built an AI agent using Composio, Vapi, and OpenAI TTS integrated with Gmail, Slack, and Google Calendar. It can summarise emails, schedule meetings, and search for Slack messages. Your entire morning routine is stress-free. The entire thing was built using Claude Code inside the Cursor IDE. Checking Slack and Gmail is a morning ritual I religiously follow, but comprehending each message while still half-asleep feels like swimming through molasses. Voice agents excel at this exact problem - you can ask them to summarise the critical stuff, explain confusing threads, or drill into specific details while you …  ( 9 min )

You know that old saying about projects: "Fast, cheap, good – pick two"? Well, blockchain has its own version of this cruel joke, and it's been driving developers crazy for over a decade. Welcome to the blockchain trilemma, where you get to choose between decentralization, security, and scalability but you can only have two. It's like being forced to pick your favorite child, except your children are fundamental properties of a distributed network, and the stakes are billions of dollars. Let's break down what we're actually talking about here. Decentralization means no single entity controls the network. Think thousands of nodes scattered across the globe, each with equal say in what transactions are valid. It's democracy for databases. Security means the network can't be hacked, manipulat…  ( 9 min )

The golden age of free artificial intelligence is drawing to a close. For years, tech giants have poured billions into subsidising AI services, offering sophisticated chatbots, image generators, and coding assistants at prices far below their true cost. This strategy, designed to capture market share in the nascent AI economy, has democratised access to cutting-edge technology. But as investor patience wears thin and demands for profitability intensify, the era of loss-leading AI services faces an existential reckoning. The implications stretch far beyond Silicon Valley boardrooms—millions of users who've grown accustomed to free AI tools may soon find themselves priced out of the very technologies that promised to level the playing field.

As developers, we love building things. But let’s be honest — spending hours managing cloud infrastructure, debugging misconfigurations, or fixing scaling issues isn’t the most exciting part of our job. The cloud gives us flexibility, but it also brings complexity. That’s where Managed Cloud Services come in. Instead of babysitting servers and pipelines, you can offload monitoring, security, and optimization to experts — while you focus on writing code and shipping features. The Problem: Cloud Complexity Is Real Cloud adoption has skyrocketed. Most teams are now using multi-cloud environments (AWS, Azure, GCP), containers, Kubernetes, and CI/CD pipelines.

Day 8 of my LeetCode streak 🚀 Today’s problem was 165. Compare Version Numbers — a neat string parsing challenge where the tricky part isn’t the logic itself, but handling all the little details: Ignoring leading zeros ("01" = "001") Treating missing revisions as 0 ("1.0" = "1.0.0") Comparing uneven revision lengths I solved it in JavaScript by splitting the version strings into arrays, comparing each part as integers, and defaulting to 0 when one version runs out of parts. Even on a distracted day (hello, Twitter doomscrolling 😅), keeping the streak alive matters. 👉 Full breakdown with code and reflections on my blog: https://nitinahirwal.in/posts/165-CompareVersionNumbers On to Day 9! 🚀 LeetCode #JavaScript #100DaysOfCode  ( 6 min )

In one of my older writings, I argued that “asking the right question” was the golden key to getting quick and useful answers from people. Back then, developer communities, forums, and Telegram groups were the holy grounds where our questions lived. Everyone had Google, but the real magic was asking the right people in the right way. Ask poorly, and you’d either get mocked or dismissed with: “Dude, do your own research first.” Today, things are different. Instead of bad-tempered humans, we now face an always-eager, sometimes confused AI. Large Language Models (LLMs) like ChatGPT have rewritten the rules of the game.

Hi Dev Community, I'm Nauman! I’m currently learning frontend development in Bahawalpur, Pakistan, and this is my story—raw, real, and still unfolding. I didn’t come from a tech background, but I’ve always been curious about how websites work behind the scenes. That curiosity led me to enroll in a web development course at Corvit BWP, and it’s been a rollercoaster ever since. JavaScript hit me like a storm—especially asynchronous concepts like callbacks and Promises. I remember staring at code, wondering why things weren’t working, feeling stuck and overwhelmed. But I didn’t give up. I started asking questions, breaking problems into tiny pieces, and using analogies to make sense of the chaos. Slowly, things began to click. I realized I learn best through real-world examples, visual explanations, and hands-on practice. I started solving small challenges, building mini-projects, and writing down what I understood. That’s why I’m here on Dev.to—to share what I’ve learned in a way that helps others who might be facing the same confusion. I want to turn my learning into something useful for others. My goal is to write beginner-friendly blogs that simplify tough topics, especially for those who feel lost in callback hell or tangled in JavaScript logic. If my posts can help even one person feel more confident, that’s a win. I’m exploring modern tools like Next.js and MongoDB, and I’m excited to share tutorials, breakdowns, and personal insights as I grow. I believe learning is a journey, not a race—and I’m here to walk it with you. Thanks for reading. Let’s build, learn, and grow together.  ( 6 min )

Introduction Artificial Intelligence (AI) is transforming how we interact with technology. Instead of hard-coding logic for every feature, developers can now offload tasks like summarization, reasoning, and content generation to Large Language Models (LLMs). Claude, created by Anthropic, is one of the newest and most powerful AI assistants available today. It competes with models like OpenAI’s GPT, but with a focus on safety, long context handling (up to 200K tokens), and strong reasoning abilities. In this article, I’ll show how Flutter, a cross-platform framework for mobile development, can integrate with Claude’s API to create AI-driven mobile applications. Why Use AI in Mobile Apps? Mobile users generate and consume text constantly — notes, emails, chats, documents, and more. Embedding…  ( 10 min )

Three months ago, I discovered a tool that completely transformed my SQL workflow. Here's my brutally honest review of the MSSQL extension for VS Code. We've all been there. You're in the zone, cranking out application code, when suddenly you need to check something in the database. Alt-tab to SSMS, wait for it to wake up from hibernation, click through a dozen dialogs to get connected, and boom—your coding flow is dead. I used to lose at least 30 minutes a day to this context switching nightmare. Until I found something that changed everything.

Introduction Running Nginx on a public server without proper hardening is a recipe for abuse. Two of the most effective, low‑maintenance defenses are TLS encryption and Fail2Ban. TLS protects data in transit, while Fail2Ban automatically bans IPs that show malicious behavior (e.g., repeated 404s or brute‑force login attempts). This tutorial walks an SRE through a practical, step‑by‑step hardening of an Ubuntu 22.04 Nginx instance. TLS eliminates eavesdropping and man‑in‑the‑middle attacks. Modern browsers also flag non‑HTTPS sites as insecure, hurting user trust. Fail2Ban watches log files for patterns that indicate attacks (failed logins, repeated 404s, etc.) and adds temporary firewall rules to block the offending IPs. Together they address both data confidentiality and automated abuse…  ( 8 min )

Mastering Session Management: The Cornerstone of Web Security Introduction In the realm of web security, session management is often the unsung hero. While encryption and authentication grab headlines, how a web application manages user sessions can make or break its security posture. Sessions are the threads that weave a user's journey through a website, maintaining state and identity across multiple requests. However, if not handled properly, sessions become a gateway for attackers to hijack accounts, steal sensitive data, or impersonate users. Understanding Sessions and Their Importance A session represents a semi-permanent interactive information interchange between two or more communicating devices, typically a user and a web server. HTTP is stateless by design, so sessions help maint…  ( 8 min )

Introduction So when it comes to memory management there are two terms you really need to know, the stack and the heap. The stack is a region of memory that stores temporary data that is only needed for a short period of time. It operates in a last-in, first-out (LIFO) manner, meaning that the most recently added data is the first to be removed, as the name suggests. Basically imagine a stack of plates, if you wanna remove one plate you remove the top one, remove the middle plate and disaster awaits in this analogy. The stack is typically used for storing function parameters, local variables, and return addresses. It is fast and efficient because it has a fixed size and does not require dynamic memory allocation. The size of the stack is usually limited, and if a program tries to use mor…  ( 14 min )

In the early days of microservices, REST APIs became the default way for services to talk to each other. They’re simple, predictable, and well-understood. But as systems grow, REST starts showing cracks: latency, bottlenecks, and brittle dependencies. That’s where asynchronous messaging with tools like Kafka, RabbitMQ, or Azure Service Bus takes the lead. REST APIs force a request–response relationship. If Service A calls Service B, A must wait until B replies. Messaging flips this. A just sends a message and moves on. B (and even C, D, E…) can consume it when ready. 👉 This decoupling makes systems more resilient—one slow service doesn’t break the whole chain. With REST APIs, the producer is in push mode. The caller must hit the server directly, regardless of whether that server is busy, …  ( 7 min )

Multithreading is the process of executing multiple threads simultaneously. A thread is the smallest unit of execution. Java provides strong multithreading support via the Thread class and Runnable interface. It helps in better CPU utilization and improved application performance. There are two main ways to create a thread in Java: a) Extending the Thread Class class MyThread extends Thread { public void run() { System.out.println("Thread running using Thread class!"); } } public class ThreadDemo { public static void main(String[] args) { MyThread t1 = new MyThread(); t1.start(); // Start the thread } } b) Implementing the Runnable Interface class MyRunnable implements Runnable { public void run() { System.out.println("Thread running using Runnable interface!"); } } public class RunnableDemo { public static void main(String[] args) { Thread t1 = new Thread(new MyRunnable()); t1.start(); } } A thread passes through these states: New → Runnable → Running → Waiting → Terminated New: Thread object created but not started. Runnable: Thread is ready to run but waiting for CPU scheduling. Running: Thread is currently executing. Waiting/Timed Waiting: Thread is paused temporarily. Terminated: Thread has finished execution. start() → begin thread execution run() → contains the logic of the thread sleep(ms) → pause thread for given milliseconds join() → wait for a thread to finish isAlive() → check if thread is running When multiple threads access a shared resource, race conditions may occur. synchronized keyword ensures that only one thread can access a resource at a time. Threads allow concurrent execution. Two ways to create threads: Thread class & Runnable interface. Use synchronization to prevent race conditions. Multithreading is widely used in games, web servers, and real-time applications.  ( 6 min )

Next.js App Router defaults all components to Server Components. The "use client" directive marks a file as a Client Component. Placed at the top of a file: "use client"; Tells Next.js: render this component on the client (browser). Without it → the file stays a Server Component. // Button.tsx "use client"; export default function Button() { return alert("Clicked!")}>Click me } Without "use client", this would break: event handlers & useState only work in the browser. Next.js defaults to Server Components for speed & smaller bundles. "use client" is an escape hatch when you need client-only features. You need "use client" if you use: React hooks: useState, useEffect, useRef Event handlers: onClick, onChange, … Browser APIs: localStorage, window, document Client-only libraries: Chart.js, React-Quill, etc. Next.js scans for "use client" at build time. That file + its imports → shipped as JS bundle to the browser. Server Components are stripped to HTML + serialized props. Server Components can import Client Components. Client Components cannot import Server Components. // page.tsx (Server Component) import Button from "./Button"; export default function Page() { return ( Hello // Client-side, interactive ); } Default = Server Component (fast, no client JS). Add "use client" only where you need state, events, or browser APIs. Sprinkle sparingly → keep most of your tree on the server. ⚡ "use client" is the switch that brings React interactivity into your Next.js App Router components.

AbortController is the standard way to cancel async work in modern JavaScript. It pairs with AbortSignal, which you pass to tasks so they can stop immediately. Create a controller → pass controller.signal to your async work. Call controller.abort(reason?) to cancel; consumers see an AbortError (or signal.reason). Works with fetch, streams, and your own functions. const c = new AbortController() const resP = fetch('/api/data', { signal: c.signal }) // later... c.abort('user navigated away') try { await resP } catch (e) { if (e.name === 'AbortError') /* ignore */ } reason support) const c = new AbortController() const { signal } = c signal.aborted // boolean signal.reason // any (why it was aborted) c.abort(new DOMException('Timeout', 'AbortError')) // or: c.abor…  ( 8 min )

1. Stack (LIFO – Last In, First Out) A Stack follows the principle of Last In, First Out (LIFO). Think of a stack of plates: the last plate placed on top is the first one to be removed. Common Methods in Stack: push() – add an element pop() – remove top element peek() – see top element without removing isEmpty() – check if stack is empty Example Code (Stack Demo): import java.util.Stack; public class StackDemo { public static void main(String[] args) { Stack stack = new Stack(); stack.push(10); stack.push(20); stack.push(30); System.out.println("Top element: " + stack.peek()); // 30 System.out.println("Removed: " + stack.pop()); // 30 System.out.println("Is stack empty? " + stack.isEmpty()); } } 2. Queue (FIFO – First In, First Out) A Queue follows the principle of First In, First Out (FIFO). Think of a ticket counter queue: the first person in line is the first to be served. Common Methods in Queue: offer() – add element poll() – remove front element peek() – see front element isEmpty() – check if queue is empty Example Code (Queue Demo): import java.util.LinkedList; import java.util.Queue; public class QueueDemo { public static void main(String[] args) { Queue queue = new LinkedList(); queue.offer(10); queue.offer(20); queue.offer(30); System.out.println("Front element: " + queue.peek()); // 10 System.out.println("Removed: " + queue.poll()); // 10 System.out.println("Is queue empty? " + queue.isEmpty()); } } Stack is best when you need reverse order processing (Undo operations, DFS, expression evaluation). Queue is best when you need sequential order processing (Task scheduling, BFS, request handling).  ( 6 min )

Internationalization (i18n) is the blueprint for global software. At its heart lies a deceptively simple element: the translation key. Your team's approach to naming these keys isn't a minor detail—it's a foundational architectural decision. A poor strategy creates "i18n debt," a silent tax on every future feature that slows development and inflates costs. A great one ensures longevity and streamlines collaboration for years to come. Think of an i18n key not as a variable, but as a stable, multi-party contract between three stakeholders: Developers: They need a predictable interface to retrieve text. The key should offer clues about a string's purpose, reducing the need to constantly jump between the codebase and translation files. Translators: The key is often their first and most impor…  ( 12 min )

In addition, Proxmox can handle so-called containers via LXC (Linux Containers), which are even lighter than VMs and great for running individual applications with minimal overhead. You also can manage your VMs and containers from a browser. Web-based interface designed to be user-friendly, so even those new to virtualization can get started without too much trouble.

As developers and designers, we've all been there. You're working on a new feature, and you need to use the brand's primary color. You open the inspector, find a button that looks right, and copy the hex code: #3B82F6. A week later, another developer does the same but samples it from a slightly different banner and gets #3B83F7. Individually, these tiny inconsistencies are harmless. But they accumulate. Over time, your application's UI becomes a patchwork of "almost-right" values, leading to a messy user experience and a maintenance nightmare. This is the problem that Design Tokens solve. At their core, design tokens are a methodology for managing your design decisions. They are named entities that store the individual, low-level values of your design system, like colors, spacing, typograp…  ( 8 min )

No soy un usuario avanzado de herramientas de IA, sin embargo en el último AWS Meetup Madrid, nos acompañó Alejandro Veliz Fernandes como uno de los ponentes. Durante su charla en demos interactivas nos mostró una visión general de cómo funciona KIRO, entrando en detalles en la parte que más me interesa de la IA, los límites de la herramienta (Guard rail) y la seguridad de nuestra información.

Serverless architecture has revolutionized how we build applications, but it comes with a well-known Achilles' heel: managing state. For stateless functions, it’s a dream. But as soon as your application requires real-time collaboration, live presence, or persistent chat, you enter a world of complexity. How do you manage WebSocket connections when your functions are ephemeral? The traditional workarounds are often complex and costly. You might find yourself managing sticky sessions on load balancers or bolting on a separate stateful service like Redis just to handle pub/sub and connection mapping. This adds significant operational overhead, undermining the core promise of serverless. At Vaultrice, we faced this exact dilemma. We needed to build a global, low-latency, and strongly-consiste…  ( 8 min )

I’m genuinely curious. For those of you managing servers day to day: Do you find SSH still works fine for you? Or do you run into pain points (key management, VPN drops, onboarding/offboarding, lack of auditing, etc.)? If you could design the ideal way to access and manage servers, what would it look like? I work at a team that’s exploring a new approach to server access. But before anything else, I want to hear directly from the community. What are your real frustrations? What would make your lives easier? We’ve also opened a Discord community where we’re talking about DevOps, security, and new ways to approach infra access. 👉 Join here I’d love to get your perspectives and learn what matters most to you.  ( 6 min )

React Native has become one of the most popular frameworks for building cross-platform mobile applications. It allows developers to write apps in JavaScript or TypeScript and run them on both iOS and Android with near-native performance. But when you start building your first project, you’ll face a crucial decision: Expo vs Bare workflow in React Native. This choice directly impacts how you develop, configure, and deploy your application. In this article, we’ll dive deep into the React Native Expo vs Bare workflow debate, explore their advantages and limitations, and answer common questions like “Which is better: Expo or Bare workflow in React Native?” and “Can I switch from Expo to Bare workflow later?” The Expo managed workflow is often the go-to choice for beginners. Expo provides a s…  ( 9 min )

Wallet onboarding solutions have improved significantly over the last couple of years. While Dynamic.xyz has been a popular option, there are some differences in behavior across platforms that are worth noting. One example is how wallet disconnections are handled in MetaMask. In @dynamic-labs/sdk-react-core@4.32.0, the useIsLoggedIn() hook does not update to false when disconnecting a wallet. This behavior is noticeable not just in code but also on the Dynamic.xyz demo website, where disconnecting the wallet does not log out the user automatically. In contrast, both Privy.io and Web3Auth demos handle disconnects as expected, updating the state and logging the user out when the wallet is disconnected. Developed by the Metamask team. Offers reliable wallet disconnection handling. Supports social login flows alongside decentralized wallets. Provides cross-platform support including browser, mobile, and Unity. Developed and backed by Stripe. Handles wallet disconnections reliably. Supports account abstraction and embedded wallets. Focuses on privacy-first authentication and encrypted data management. From a personal perspective, backing by well-known teams adds confidence in terms of long-term support and reliability. Feature Dynamic.xyz Web3Auth Privy.io Wallet disconnect sync Does not update Yes Yes Social login Limited Yes Yes Account abstraction Partial Optional Default Reliability Generally good Strong Strong Backed by popular teams Medium Metamask team Stripe All three platforms offer wallet onboarding capabilities, but Web3Auth and Privy.io provide additional confidence with reliable disconnect handling and backing from prominent teams.

Unit Of Work.. What is it ? The Unit of Work pattern is a design pattern used to group multiple operations (usually repository calls) into a single transaction. It ensures that either all operations succeed or none are applied, maintaining data consistency. It usually works alongside the Repository pattern, which abstracts data access logic. As I said it can work with repository patten, I will keep the code fairly simple rather than over-complicating it with generic repository. // Models/Product.cs public class Product { public int Id { get; set; } public string Name { get; set; } public decimal Price { get; set; } } // Models/Order.cs public class Order { public int Id { get; set; } public int ProductId { get; set; } public DateTime OrderDate { get; set; } } //…  ( 8 min )

In this blog, we’ll walk through how our Angular application is architected to work with a dynamic CMS setup using a custom library that acts as the bridge between Optimizely CMS and frontend rendering. We’ll explore the folder structure, routing flow, component loading, and how the** dynamic component** architecture works behind the scenes. Our Angular application is organized into three main folders: 1. DropComponents Contains all components that are dropped via CMS into the PageComponents array or the Blocks drop in CMS Content area. These components are dynamically rendered using a custom directive provided by our Angular library. 2. GlobalComponents Contains global UI components such as Header and NotFoundComponent (404 page) etc. 3. Pages Contains route-based page components. Include…  ( 13 min )

When developing modern applications, it’s common to hit a roadblock because the real backend service isn’t ready, or you need to test against multiple APIs at once. That’s where a mock server comes in: a lightweight server that returns fake data and files to mimic the behavior of your real backend. Python is an excellent choice for building mock servers because: It ships with a built-in HTTP server. It has lightweight frameworks like Flask and FastAPI. It can scale from a quick one-liner to a production-like simulation. In this guide, we’ll cover all Python-based options — from serving static files, to full CRUD APIs, to enterprise-style mocking. Python ships with http.server, a simple web server module. It’s the fastest way to expose a directory of files over HTTP. python3 -m http.server …  ( 9 min )

What Is Sentence-Transformers (SBERT)? When I first explored text similarity, it was for an exam management system. The problem? Sometimes different teachers unknowingly entered the same question twice in the database just phrased a little differently. Traditional keyword-based matching struggled with this, since two questions could look different on the surface but actually mean the same thing. For example: “What is the capital city of France?” To a keyword search, those might look different. But to a student (and to us), they’re clearly duplicates. This is where Sentence-Transformers (SBERT) comes in. By converting questions into semantic embeddings, SBERT allows us to measure how close two sentences are in meaning, not just in wording. That makes it perfect for detecting duplicate que…  ( 11 min )

Artificial intelligence tools like ChatGPT are great at generating text, but they don’t always “know” everything. Their knowledge is limited to what they were trained on, and that training data stops at a certain date. So, what happens if you want your AI to answer questions about new research, company documents, or yesterday’s news? That’s where RAG (Retrieval-Augmented Generation) comes in. What is RAG? RAG stands for Retrieval-Augmented Generation. It’s a technique that makes large language models (LLMs) smarter by connecting them to an external knowledge source. In simple terms: Retrieval = finding relevant information from a database, documents, or the internet. Generation = using that information to create a human-like answer. Think of it like this: How RAG Works (Step by Step) User …  ( 7 min )

Voy a dar mi opinión personal. Creo que es una pregunta con una respuesta difícil y que depende más de los puntos de vista. Desde mi punto de vista como persona que ha asistido a varias charlas, la verdad es que la Camp ha sido interesante, quizás para mi gusto demasiada IA, pero no podemos negar que ahora mismo la IA es lo que está tirando de una parte importante del carro de la innovación en el sector de la informática/tecnología tanto a nivel de desarrollo y mejoras como de inversión económica, pero mi sensación es que después del pico del hype que hemos sufrido con la IA estamos en estos momentos en un momento meseta y no tengo claro si de aquí volverá a subir o tendrá una caída. También he echado en falta charlas más transversales que no sea únicamente Drupal, o en las que Drupal es…  ( 7 min )

Hey guys! It's great to be back! After a short break, I'm thrilled to dive back into the world of React with a topic that's central to modern web development: the big shift from class components to functional ones. The evolution of React from class components to functional components isn't just a simple facelift or a change in syntax—it represents a profound shift in how we approach component design and manage complexity. It's an intentional move toward making React codebases more predictable, understandable, and reusable. Before the introduction of Hooks, the primary way to build stateful, complex components was through the class component model. While powerful, they introduced several pain points that often led to confusion and verbose code: Complex this Context: Class components rely he…  ( 8 min )

Introduction When people think about machine learning, their attention often gravitates toward sophisticated algorithms like random forests, neural networks, or support vector machines. However, in practice, success in machine learning is not just about choosing the right model; it is about choosing the right features to feed into those models. The data we use has just as much influence on performance as the algorithm itself. If the dataset is bloated with unnecessary, irrelevant, or noisy features, even the best algorithms may struggle to produce accurate predictions. On the other hand, if we carefully select the features that matter most, our models become more interpretable, faster, and better at generalizing to unseen data. This process of identifying and selecting relevant variables i…  ( 11 min )

Migrating a large-scale production application is never a small decision especially when the application in question is powering wallet operations, bill payments and crypto-to-fiat conversions. For context, the system I worked on had grown beyond 120,000 lines of JavaScript, much of it mission-critical and actively serving users with real money flowing through it every single day. The push to migrate wasn’t just my personal, although I’d long advocated for TypeScript internally. The tipping point came through a combination of colleague feedback, developer pain around ongoing maintenance, and the long-term risks of leaving such a large system in “pure JavaScript mode.” I should also note that this work was heavily inspired by Ben Howdle.

PHP JIT Compiler: How It Works and Why It Matters Introduction PHP has traditionally been an interpreted language, which means that every time you run your PHP code, the Zend Engine parses and executes it line by line. With the release of PHP 8.0, a new feature called JIT (Just-In-Time) Compiler was introduced. JIT can significantly speed up certain types of operations by compiling PHP code into machine-level instructions that the CPU can execute directly. In this blog, we’ll explore: What JIT is and how it works in PHP How PHP worked before JIT A practical example showing the performance difference with and without JIT When JIT is most effective JIT (Just-In-Time) Compilation is a technique used by modern programming languages to improve performance.

The Butterfly Effect That Started It All Three years ago, I never imagined that sharing my YouTube earnings on Medium would lead to building a SaaS platform. But that's exactly what happened when a young programmer named Timur slid into my DMs after reading about my faceless YouTube channels and print-on-demand success. That single DM would become the foundation of ToolsTube, our all-in-one YouTube SEO platform that's launching today on Product Hunt. The Developer's Dilemma Working with Timur opened my eyes to something fascinating about backend developers. They're absolute wizards at solving problems, but there's a catch. They tend to focus intensely on developer problems and want to solve them with code, only to discover that hundreds of other developers have already built similar soluti…  ( 8 min )

This article provides a side-by-side comparison of the most common query operators in Shodan vs the latest syntax in ZoomEye. When it comes to cyberspace search engines, Shodan and ZoomEye are two of the most widely used platforms. Shodan is often described as “the search engine for the Internet of Things,” indexing banners and metadata from connected devices worldwide. ZoomEye, is another powerful search engine for internet-wide scanning, particularly popular in the security research community. Both platforms allow analysts, penetration testers, and defenders to search for exposed services, vulnerable hosts, and network fingerprints. However, their query syntax is different — and mixing them up can lead to zero results or misleading queries. Find exposed RDP (3389) assets Shodan: po…  ( 6 min )
